Efficient Discriminative Learning of Parts-based Models (2009)
Kumar, M. Pawan, Torr, Philip, Zisserman, Andrew
Supervised learning of a parts-based model can be formulated as an optimization problem with a large (exponential in the number of parts) set of constraints. We show how this seemingly difficult...
P³ & Beyond: Move Making Algorithms for Solving Higher Order Functions (2009)
Kohli, Pushmeet, Kumar, M. Pawan, Torr, Philip
In this paper, we extend the class of energy functions for which the optimal alpha-expansion and alpha beta-swap moves can be computed in polynomial time. Specifically, we introduce a novel family of...
Discrete contours in multiple views: Approximation and recognition (2004)
M. Pawan Kumar, Saurabh Goyal, Sujit Kuthirummal, C. V. Jawahar, P. J. Narayanan
Recognition of discrete planar contours under similarity transformations has received a lot of attention but little work has been reported on recognizing them under more general transformations....
Planar Homography From Fourier Domain Representation (2004)
Pawan Kumar Sujit, M. Pawan Kumar, Sujit Kuthirummal, C. V. Jawahar, P. J. Narayanan
Computing the transformation between two views of a planar scene is an important step in many computer vision applications. Spatial approaches to solve this problem need corresponding sets of...
Discrete contours in multiple views: approximation and recognition (2004)
Pawan Kumar Saurabh, M. Pawan Kumar, Saurabh Goyal, Sujit Kuthirummal, C. V. Jawahar, P. J. Narayanan
Recognition of discrete planar contours under similarity transformations has received a lot of attention but little work has been reported on recognizing them under more general transformations....
Learning layered pictorial structures from video (2004)
We propose a new unsupervised learning method to obtain a layered pictorial structure (LPS) representation of an articulated object from video sequences. It will be seen that this is related in turn...
Polygonal Approximation of Closed Curves across Multiple Views (2002)
M. Pawan Kumar, Saurabh Goyal, C. V. Jawahar, Kumar Saurabh, P. J. Narayanan
Polygon approximation is an important step in the recognition of planar shapes. Traditional polygonal approximation algorithms handle only images that are related by a similarity transformation. The...
