| | Projects |
A selected list of projects with which I was associated.
Virtual Advertisements:
The project was to artificially render dynamic advertisements on some static billboards in a real scene as it is
being captured in a video-footage. The issues involved were real-time segmentation of occluders
and simple geometric etchniques to enable the transfer of the required texture on the billboard. For a detailed
report and some demos visit
http://www.cse.iitd.ernet.in/vglab/
Augmented Reality:
The project involved developing a novel technique for simple and fast augmentation of a static scene
with artificial moving objects or objects extracted from a motion clip. The technique essentially deals
with the recovery of camera parameters of the static image followed by a sparse modeling of the potential
occluders. A detailed report and some demos can be accessed at
http://www.cse.iitd.ernet.in/vglab/
Robot Navigation:
The project involved developing a robot navigation system, in which a robot, with mounted cameras,
can detect obstructions, and traverse a path avoiding them, from its starting position to the designated destination.

Image based Rendering of Walk-through:
Recently, the problem of image based rendering has attracted considerable attention wherein the environmental
map for rendering of novel views are maintained in terms of a set of images instead of explicit geometric
and photommetric models of a scene. The project addressed the problem of generation of a sequence of novel views
of a scene from a set of reference views. To access a detailed report and some demos visit

Volume Rendering on GPU:
Volume Rendering has long been used for medical imaging, fluid dynamics and other such applications where information from 3D data is to be extracted. Due to large data sizes and intensive computations it has long been a classical problem in graphics. The recent emergence of hardware accelerated algorithms have furthered these applications and allows real time rendering. The project was to implement and analyse different techniques for rendering volumetric data and utilisation of GPU for achieving real-time interactive visualization.
