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.
