How Rev Eye Works For Tech Geeks

 Augmented Reality is no longer confined to our dreams and has now become a part of our tech infused lives . So we won’t take the trouble of explaining what this piece of Utopian art is. But what we will do is flaunt our pretty legs and talk about one AR app in particular – Rev Eye. You can say we are being shameless, or maybe not, because at the moment Rev Eye is the most feature rich AR app in the market! So, let’s talk cool, geeky tech details!

We use few feature detection algorithms as raw ingredients on the first layer. It is cooked by app making languages and garnished by best UI turning into a beautiful Dish called Rev Eye. Guys and girls can give it a shot for the damn high prize of 0$ but the feel you get is around 10^6 Dollars (Yea, I got a technical figure over here woooHoHOOOO).

Couple of years back a cool watch was all you needed to pass for a grown-up in a student bar, no you need smart wearable technologies, not any old watch that can just show the time and sparkle some diamonds. So, what are wearable technologies all about? What is Augmented Reality about? What are gaming consoles like Oculus Rift and Project Morpheus about? Voice search? Gesture commands? Let’s explore together, my fellow technoholics

Now, lets strictly get into technical aspects. We use SIFT and STAR for Object or Detection.When we say object, it can be anything which our database is trained to recognize. Bon voyage, now we are getting into deep blue sea. SIFT before entering into the actual algorithm one has to be aware of  two concepts:

  1. Key point detection: They are Points of interest which are identified across both image and scale dimensions using a “saliency”(similarity) criterion in order to boost efficiency of computation. Keypoints are detected in octave layers of the image pyramid as well as in layers in-between. The location and the scale of each keypoint is obtained in the continuous domain via quadratic function fitting. Whoa! Lots of technical specs!

  2. Key point description: A sampling pattern consisting of points lying on appropriately scaled concentric circles is applied at the neighborhood of each keypoint to retrieve gray values processing local intensity gradients, the feature characteristic direction is determined.

Images may vary in sizes, clarity and lot of noise may interfere. To sustain such variations and give the same results we subject the real time image to various procedures. First thing is to do Gaussian Blur and subject the image to scaling.

Octaves and Scales:

The number of octaves  depends on the size of the original image. While programming SIFT, you’ll have to decide for yourself how many octaves  you want. However, the creator of the algorithm SIFT David Lowe, suggests that 4 octaves and 5 blur levels are ideal for the algorithm. In the next step, we’ll use all these octaves to generate Difference of Gaussian images.

Difference of Gaussian:

Once DoGs are found, images are searched for local extrema over scale and space. For example, one pixel in an image is compared with its 8 neighbours as well as 9 pixels in next scale and 9 pixels in previous scales. If it is a local extrema, it is a potential keypoint. It basically means that keypoint is best represented in that scale. It is shown in below image:

Keypoint Localization:

Once potential keypoints locations are found, they have to be refined to get more accurate results. They used Taylor series expansion of scale space to get more accurate location of extrema, and if the intensity at this extrema is less than a threshold value then  maxima  or minima is found.

Orientation Assignment:

Now an orientation is assigned to each keypoint to achieve invariance to image rotation. A neigbourhood is taken around the keypoint location depending on the scale and the gradient magnitude. Direction is calculated in that region. An orientation histogram with 36 bins covering 360 degrees is created. (It is weighted by gradient magnitude and gaussian-weighted circular window with \sigma equal to 1.5 times the scale of keypoint. The highest peak in the histogram is taken and any peak above 80% of it is also considered to calculate the orientation. It creates keypoints with same location and scale, but different directions. It contributes to stability of matching.

http://www.aishack.in/wp-content/uploads/2010/06/sift-orientation-window.jpg

Keypoint Descriptor:

Now keypoint descriptor is created. A 16×16 neighbourhood around the keypoint is taken. It is divided into 16 sub-blocks of 4×4 size. For each sub-block, an 8 bin orientation histogram is created. So a total of 128 bin values are available. It is represented as a vector to form keypoint descriptor. In addition to this, several measures are taken to achieve robustness against illumination changes, rotation etc.

Keypoints between two images are matched by identifying their nearest neighbours. But in some cases, the second closest-match may be very near to the first. It may happen due to noise or some other reasons. In that case, ratio of closest-distance to second-closest distance is taken.

What Now?

This is what we are efficiently and persuasively envisioning for Rev Eye in the future:

1) Real time training

2) Reverse image search against database

3) Scale and rotation invariant

4) 360 degree orientation with minimum tracking error

The Interrupted Swan Song of Asian Newspaper Industry

Surfing the net on a rainy day one can come across quite few innovative advertising campaigns using Augmented Reality, like the IKEA catalogue, Hagen Dazs ice cream violinists and National Geographic dinosaurs. Enriching content of books, magazines and newspapers with AR has slightly fallen behind the ads even though there is no reason why it should.

Last week we partnered with Deccan Chronicle, a South Indian English daily newspaper. We started by Motion Print enabling their Sunday edition cover story about “an Indian version of 50 Shades of Grey” giving a trailer to the saucy book. We also enabled one of their most read columns about food giving photo and video instructions on how to make the recipes and, lastly, the Astroguide giving cool pictures of different horoscopes and a share option.

Couple of years ago the media industry speculated that humans have grown a new vestigial limb, and that limb was newspapers. For example, in 2012 circulation had dropped by 6.6% in USA, 5.3% in Western Europe, 1.4% in Middle East and Africa. In a brotherly unison, the advertising revenues followed the circulation. Though, interestingly enough, or maybe not so much since these are developing economies, circulation grew in Asia and Latin America.

With everything digital becoming more prominent, it seemed it was time for newspapers’ Swan song. Perhaps The Beatles “Yesterday”:

Yesterday, all my troubles seemed so far away

Now it looks as though they’re here to stay

Oh, I believe in yesterday

But the newspaper folks are savvy folks. We imagine, they came together, smoked a pack or two each and started focusing on digital subscriptions. In 2013 sales started picking up, and digital advertising revenues went up by 15%. Though the somewhat late expansion in digital is still being counteracted by a reduction in newsroom staff and frequency of print, in some cases to three times a week.

The question stands – can digital save newspapers? Our answer is no and yes. No because silly, little us believe that there will always be a place for quality journalism, hence, it won’t need saving. Deeply researched, splendidly written and well timed pieces of human excellence will stand up for their own place in society. And so will the less heroic sounding but equally important feel good pieces about recipes, gardening, outfits and animals meant to be read on a late Sunday morning before the farmers market, during your second cup of coffee and after the Sunday morning frolicking with your significant other. And before the day comes when really good, free internet access covers the whole globe and smartphones and tablets are a birthright, newspapers will have their place in our lives.

The yes goes for what digital can offer, which is cost saving reach – a platform for all the great journalism already being done -, and extra content .And, of course, digital can save newspapers from becoming ad dumpsters. Everyone has seen the free papers filled with nothing but ads practically shoved down our throats on streets .

Newspapers going digital are creating a usage pattern that we are going to attempt to brand as ‘second engagement’. When a story in a paper interests us, we will read it and then go online and try to find more information on the subject. Or find the same information for the purpose of sharing it with our social circle.

Deccan Chronicle Motion Print

Now, how great was it if a well developed digital platform of the same newspaper was the first thing in our search results? Here is the catch, Deccan Chronicle Motion Print articles are giving the extra information immediately. It is right there – read, care, share. Plus, the digital overlay of share buttons with predisposed hashtags and links is driving people to the paper’s online assets . Starting with Motion Print content means that by the time advertisers come knocking interested in exploring opportunities of Motion Print, a paper already has an audience adapted to using Augmented Reality.

Western newspapers were pushed into digital after the decline in circulation. We can only agree with the print industry of Asia that going into digital before suffering losses is the smart thing since it does not seem that the civilization will be returning to stone age any time soon. We stick to our words, even if it does sound slightly presumptuous.

The Luxury Box

Rev Eye powers the world’s only Motion Print luxury tabloid!

What we are extremely excited about is the launch of the world’s only Motion Print luxury tabloid The Luxury Box, envisioned by the organizers of The Indian Luxury Expo in partnership with Rev Eye. The Luxury Box is fully enabled with Rev Eye, meaning that when you will read the cover story on Aston Martin Rapide S and scan the image, you will feel as if the car is right in front of you!

Check out the video of the Aston Martin cover story to see, what happens, when you scan The Luxury Box with Rev Eye:

Just in case you are interested, The Luxury Box is currently available in the biggest stores in Hyderabad, India with a nationwide launch upcoming…who are we kidding, of course you are interested! :) Click here to check out the map showing stores in which you can get your hands on The Luxury Box.

World’s only Motion Print luxury tabloid

So, why did we partner with Jukebox Media and decide to shake up the luxury industry with a pioneering product that has no equivalent anywhere in the world (hence we had no clue, how it would go down with customers)? First of all, because we all are on this crazy adventure called life and risks should be taken. Secondly because our experience with the Indian Luxury Expo proved us that Augmented Reality and luxury are perfect for each other.

Rev Eye Motion Print is not a pretty trinket or an add-on, it brings value to customer and brand interactions. Customer attention span is decreasing and with so many commodities to choose from, customers need to feel a connection to a brand, identify it as ‘their kind of brand’. Especially it goes for luxury items.

The cost and status symbol of which means people who own them enter into a special, often, lifelong relationship with the brand. Rev Eye Motion Print can facilitate formation of this relationship like no other form of advertising.

Take a luxury car ad printed in an upscale magazine, like the Aston Martin Rapide S in the video. When a user scans the ad, the picture of the car would turn into a 3D model that can be rotated to view it from different angles. Tap on different parts of the car and get technical specifications. Change the color of the paint and material of the seats. Customize the car in every way you like. And, finally, call a private number, that can only be unlocked through Rev Eye, to get exclusive access before anyone else.

Rev Eye Motion Prints emphasize the VIP relationships luxury brands have with their clients.

Like The Luxury Box Facebook page to find out first when the world’s only #MotionPrint luxury tabloid is coming to your city!  Cheers to crazy adventures and new ideas!

What Sci-Fi, Gizmos and Motion Print have In Common

The sun is slowly setting. But you don’t see it because you are at a desk, surrounded by other desks, surrounded by walls and low hanging ceilings. When you think about it, you haven’t seen the sun in quite a while. A lowly strip of a shredded paper timidly blows by carried by the breeze coming from the outside world. Your boss walks by and gives you a blank stare. You give one back. You have nothing in common. The printer is regurgitating a piece of an excel form. The sound perfectly encapsulates how you feel about your work day.

Alright, that’s exaggerated! You must be really unlucky to be so miserable at work. However, for most of us, it is true that the everyday isn’t good enough everyday (if you are one of those overly perky people who share inspirational quotes on Facebook, apologies). We love Sci-Fi because it is a pure, unadulterated form of escapism. It takes you beyond where any travel guide could.

The wise fantasy author, David Eddings, has said, “Fantasy takes people away from the real world and almost everybody dislikes the real world.”

And what about the gizmos! Any person who admits they have never fantasized about victoriously commanding a four legged AT-AT Walker used by the Imperial ground forces, or never has wanted to posses a Time Turner given by Dumbledore to Hermione, or a Deluminator to absorb and return light from any room should be looked at very suspiciously.

This year Rev Eye participated in the beacon of events celebrating popular culture Comic Con India. We were there together Bahubali the two part Indian epic movie to be released in 2015. Bahubali has partnered with us and we have created a Motion Print poster for the movie. Check it out!

A recent article on an Augmented Reality convention said that one of the topics discussed was“The psycho-social implications of augmented reality vs. virtual reality, and how it could negatively affect a generation raised to interact with objects that aren’t “real,”.

Why do we need things that are not real’? Things like Rev Eye Motion Print. Why did we at Rev Eye spent an enticing hour violating Harry Potter and Yoda images, as our way of showing respect to these, in our mind, great cultural icons? Escapism is definitely top of the list, but not only. Augmented Reality, Sci-Fi and Motion Print all have another thing in common – they are portals to the ‘batshit crazy’ imaginative world children, artists and homeless people who talk to themselves have. It is not just about escaping, it is about creating. Interacting with objects that ‘aren’t real creates a dimension of limitless possibilities, and once you can imagine yourself being somewhere else, doing something else, it is just one step from there to quitting that soul sacking job and becoming a starving, yet potentially happy artist somewhere in the Bahamas.
