Part of book or chapter of book
Open AccessThe aim of this paper is to present a new algorithm to compute the distance between ndimensional histograms. There are some domains such as pattern recognition or image retrieval that use the distance between histograms ... -
A new graph matching method for point-set correspondence using the EM algorithm and Softassign
(2012)
Article
Restricted access - publisher's policyFinding correspondences between two point-sets is a common step in many vision applications (e.g., image matching or shape retrieval). We present a graph matching method to solve the point-set correspondence problem, which ... -
A new relational geometric feature for human action recognition
(Springer, 2015-01)
Article
Restricted access - publisher's policyPose-based features have demonstrated to outperform low-levelappearance features in human action recognition. New RGB-D cameras provide locations of human joints with which geometric correspondences can be easily calculated. ... -
