Unconstrained Motion Deblurring for Dual-lens Cameras
Mahesh Mohan M. R., Sharath Girish, and A. N. Rajagopalan
ICCV, 2019   (Oral Presentation)
paper / slides / poster / bib

Motion deblurring for dual-lens cameras possess an ill-posedness, which calls for a prior for depth-consistent deblurring.

Divide and Conquer for Full-resolution Light Field Deblurring
Mahesh Mohan M. R. and A. N. Rajagopalan
CVPR, 2018
paper/ slides / poster / bib

Full-resolution light field deblurring can be divided into independent subtasks, wherein a single task reinforces other tasks.

Occlusion-Aware Rolling Shutter Rectification of 3D Scenes
Subeesh Vasu , Mahesh Mohan M. R., and A. N. Rajagopalan
CVPR, 2018
paper / poster / bib

A method for the scenario of a fast moving camera wherein rolling shutter distortions results in intra-frame occlusions.

Going Unconstrained with Rolling Shutter Deblurring
Mahesh Mohan M. R., A. N. Rajagopalan , and Guna Seetharaman
ICCV, 2017
paper / slides / poster / bib

How can we bridge today's ubiquitous rolling shutter cameras with the well-studied conventional cameras, pertaining to motion deblurring?

Deep Decoupling of Defocus and Motion blur for Dynamic Segmentation
Abhijith Punnapurath , Yogesh Balaji , Mahesh Mohan M. R., and A. N. Rajagopalan
ECCV, 2016
paper / poster / bib

Deep Learning is used to obtain the attributes of object motion and camera motion, which is then employed for segmenting moving object(s).

abstract / (rest is proprietary of KLA-T; sorry.)

A fully-automatic denoising based on a convex prior on SEM images, which eradicate (difficult to infer or possibly erroneous) noise models.

A novel method of Medical Image Denoising using Bilateral and NLM filtering.
Mahesh Mohan M. R. and Sheeba V. S.,
ICACC, 2013   (Oral Presentation)
paper / technical report / slides / bib

Wavelet thresholding (Visushrink) is extended to Contourlet transform, in order to enhance the performance of bilateral and NLM filtering.
