Research Interests

I am currently interested in 3D Vision problems primarily on large scale structure-from-motion and SLAM pipelines. My recent work has been on developing methods to estimate camera motions in structure-from-motion. Previously, I was involved in development of impulse noise removal techniques from colour images.

Current Research

I am working on 3D reconstruction problems in computer vision i.e. to build a 3D representation of a scene from images. Depending on the application, it can be broadly classified as following

Depth cannot be recovered with a single image. Multiple images of the same scene is required to capture the 3D structure. Geometry of both the problems is same since both the applications use cameras. So building 3D representation requires estimating the orientation/viewing direction as well as the position of the cameras. My current work focuses on estimating orientations (also called rotation averaging) and positions of the cameras (called translation averaging).

Applications of SfM and SLAM algorithms also include 3D exploration of photo collections and phone-based augmented reality.
