Low-rank and sparse decomposition of compressively-sensed matrices: applications to surveillance video processing
Lekshmi, Ramesh (Dhirubhai Ambani Institute of Information and Communication Technology, 2015)Detection, recognition and tracking are three of the primary tasks involved in surveillance video processing. Given the huge amount of data generated by surveillance systems, it is desirable to use compressed sensing ... -
On curve reconstruction in Riemannian Manifolds: ordering motion frames
Shah, Pratik (Dhirubhai Ambani Institute of Information and Communication Technology, 2012)In this work we generalize the computational geometric curve reconstruction approach to curves embedded in Riemannian manifolds. We prove that the minimum spanning tree, given a sufficiently dense sample, correctly ... -
Road detection for intelligent transport systems
Shah, Falak (Dhirubhai Ambani Institute of Information and Communication Technology, 2015)Road detection is an important machine vision problem with applications to driver assistance systems and autonomous vehicles. We carried out a literature survey of the state of the art road detection algorithms. Simulations ... -
Similarity based regularization for online matrix- factorization problem: Application to course recommender systems
SHAH, DHRUV (Dhirubhai Ambani Institute of Information and Communication Technology, 2016)Recommender Systems have played a vital role in the emergence of e-commerce.Given a large amount of data about a user�s purchases, categorizing and generatingparameters that define each user�s behavior over a given set of ... -
Study of fuzzy clustering algorithms and enhanced fuzzy reasoning application to texture based image segmentation
Gupta, Dhruv (Dhirubhai Ambani Institute of Information and Communication Technology, 2015)c-means (k-means) is a popular algorithm for cluster analysis. Many variants of c-means algorithms are available. All these models are studied in depth and convergence of iterative solutions are verified, in this thesis. ... -
Vector graph representation for 3D meshes and algorithms for mesh deformation, enveloping, interpolation and morphing
Domadiya, Prashant Manishbhai (Dhirubhai Ambani Institute of Information and Communication Technology, 2021)The performance of the tools developed for graphics and animation depends on the underlying representation of the geometric model of the objects. The geometric model in turn describes the geometry of the real world object. ...
