NTIRE 2021 challenge on image deblurring

…, T Wang, M Suin, AN Rajagopalan… - Proceedings of the …, 2021 - openaccess.thecvf.com
Motion blur is a common photography artifact in dynamic environments that typically comes
jointly with the other types of degradation. This paper reviews the NTIRE 2021 Challenge on …

Identification of humans using gait

A Kale, A Sundaresan, AN Rajagopalan… - … on image processing, 2004 - ieeexplore.ieee.org
We propose a view-based approach to recognize humans from their gait. Two different image
features have been considered: the width of the outer contour of the binarized silhouette of …

Spatially-attentive patch-hierarchical network for adaptive motion deblurring

…, K Purohit, AN Rajagopalan - Proceedings of the IEEE …, 2020 - openaccess.thecvf.com
This paper tackles the problem of motion deblurring of dynamic scenes. Although end-to-end
fully convolutional designs have recently advanced the state-of-the-art in non-uniform …

Gait analysis for human identification

…, B Yegnanarayana, AN Rajagopalan… - Audio-and Video-Based …, 2003 - Springer
Human gait is an attractive modality for recognizing people at a distance. In this paper we
adopt an appearance-based approach to the problem of gait recognition. The width of the …

Gait-based recognition of humans using continuous HMMs

A Kale, AN Rajagopalan, N Cuntoor… - Proceedings of fifth …, 2002 - ieeexplore.ieee.org
Gait is a spatio-temporal phenomenon that typifies the motion characteristics of an individual.
In this paper, we propose a view-based approach to recognize humans through gait. The …

Off-line signature verification using DTW

AP Shanker, AN Rajagopalan - Pattern recognition letters, 2007 - Elsevier
In this paper, we propose a signature verification system based on Dynamic Time Warping (DTW).
The method works by extracting the vertical projection feature from signature images …

[BOOK][B] Depth from defocus: a real aperture imaging approach
