Continuing the tradition of technological, academic and organizational evolution of our beloved institute, my department proudly presents its first quarterly e-news letter Encode IT in December, 2019. Encode IT intends to provide a platform for faculties, students and all other stakeholders to share and receive news of latest technological advances in the field of Information and Technology. We will also be publishing achievements of staff members and students along with conducted and proposed activity schedule of the department. I expect students to be the main driving force in running this initiative. A lot of heart and hard work has gone into publishing this and every stakeholder’s involvement will encourage us further. I extend my full cooperation and best wishes to the entire team behind Encode IT.

Augmented reality (AR) adds digital content onto a live camera feed, making

that digital content look as if it is part of the physical world around you.

In practice, this could be anything from making your face look like a giraffe to

overlaying digital directions onto the physical streets around you. Augmented

reality can let you see how furniture would look in your living room, or play a

digital board game on a cereal box. All these examples require understanding the

physical world from the camera feed, i.e. The AR system must understand what

is where in the world before adding relevant digital content at the right place. This

is achieved using computer vision, which is what differentiates AR from VR,

where users get transported into completely digital worlds.

In Virtual Reality (VR), the users' perception of reality is completely based on virtual information. In

Augmented Reality (AR) the user is provided with

additional computer generated information that

enhances their perception of reality. For example,

in architecture, VR can be used to create a walk-

through simulation of the inside of a new building;

and AR can be used to show a building's structures

and systems superimposed on a real-life view.

So now that you know the meaning of AR, how

does it work? First, computer vision understands

what is in the world around the user from the

content of the camera feed. This allows it to show

digital content relevant to what the user is looking

at. This digital content is then displayed in a

realistic way, so that it looks part of the real world -

this is called rendering. Before breaking this down

into more detail, let’s use a concrete example to

make this clearer. Consider playing an augmented

reality board game using a real cereal box as the

physical support like in the figure below. First,

computer vision processes the raw image from the

camera, and recognizes the cereal box. This

triggers the game. The rendering module augments

the original frame with the AR game making sure it

precisely overlaps with the cereal box. For this it

uses the 3D position and orientation of the box

determined by computer vision. Since augmented

reality is live, all the above has to happen every

time a new frame comes from the camera. Most

modern phones work at 30 frames per second,

which gives us only 30 milliseconds to do all this. In

many cases the AR feed you see through the

camera is delayed by roughly 50 ms to allow all this

to happen, but our brain does not notice!

While our brain is extremely good at understanding

images, this remains a very difficult problem for

computers. There is a whole branch of Computer

Science dedicated to it called computer vision.

Augmented reality requires understanding the world

around the user in terms of both semantics and 3D

geometry. Semantics answers the “what?”

question, for example recognizing the cereal box,

or that there is a face in the image. Geometry

answers the “where?” question, and infers where

the cereal box or the faces are in the 3D world and

which way they are facing. Without geometry, AR

content cannot be displayed at the right place and

angle, which is essential to make it feel part of the

physical world. Often, we need to develop new

techniques for each domain. For example,

computer vision methods that work for a cereal box

are quite different from those used for a face.

For each augmented reality experience we need to

define some logic beforehand. This specifies which

digital content to trigger when something is

recognized. In the live AR system, upon recognition

the rendering module displays the relevant content

onto the camera feed, the last step in the AR

pipeline. Making this fast and realistic is very

challenging, particularly for wearable displays like

glasses (another very active area of research).

Another way to explain how AR works is to

consider computer vision as inverse rendering.

Intuitively, computer vision recognizes and

understands the 3D world from a 2D image (there

is a face and where it is in the 3D world), so that we

can add digital content (a 3D giraffe mask anchored

to the face) that is then rendered onto the 2D

phone screen.

AR is a very active field, and in the future we

expect to ee many exciting new developments.

As computer vision gets better at understanding the

world around us, AR experiences will become more

immersive and exciting.

Moreover, augmented reality today lives mostly on

smart phones, but it can happen on any device with

a camera. When enough computational power will

be available on AR glasses, we expect this medium

to make AR mainstream - enhancing the way we

live, work, shop and play.
