Segmentation and histogram generation using the HSV color space for image retrieval

S. Sural, G. Qian, S. Pramanik
Computer Science
Proceedings. International Conference on Image…
10 December 2002

We have analyzed the properties of the HSV (hue, saturation, value) color space with emphasis on the visual perception of the variation in hue, saturation and intensity values of an image pixel. Expand

Credit Card Fraud Detection Using Hidden Markov Model

A. Srivastava, A. Kundu, S. Sural, A. Majumdar
Computer Science
IEEE Transactions on Dependable and Secure…
2008

We model the sequence of operations in credit card transaction processing using a hidden Markov model (HMM) and show how it can be used for the detection of frauds. Expand

Credit card fraud detection: A fusion approach using Dempster-Shafer theory and Bayesian learning

Suvasini Panigrahi, A. Kundu, S. Sural, A. Majumdar
Computer Science
Inf. Fusion
1 October 2009

We propose a novel approach for credit card fraud detection, which combines evidences from current as well as past behavior. Expand

Gait Recognition in the Presence of Occlusion: A New Dataset and Baseline Algorithms

M. Hofmann, S. Sural, G. Rigoll
Computer Science
2011

We present a new dataset for gait recognition which addresses the problem of dynamic and static inter object occlusion. Expand

We present an approach for human fall detection using a single camera video sequence. Expand

Analyzing temporal role based access control models

Emre Uzun, V. Atluri, +4 authors P. Madhusudan
Computer Science
SACMAT '12
20 June 2012

We consider the temporal extension of Role Based Access Control (TRBAC), and develop safety analysis techniques for it. Expand

BLAST-SSAHA Hybridization for Credit Card Fraud Detection

A. Kundu, Suvasini Panigrahi, S. Sural, A. Majumdar
Computer Science
IEEE Transactions on Dependable and Secure…
1 October 2009

We propose to use two-stage sequence alignment in which a profile analyzer (PA) first determines the similarity of an incoming sequence of transactions on a given credit card with the genuine cardholder's past spending sequences. Expand

Gait recognition using Pose Kinematics and Pose Energy Image

Aditi Roy, S. Sural, Jayanta Mukherjee
Computer Science
Signal Process.
1 March 2012

We model a gait cycle using a chain of key poses and extract a novel feature called Pose Energy Image (PEI). Expand

Weighted Intra-transactional Rule Mining for Database Intrusion Detection

A. Srivastava, S. Sural, A. Majumdar
Computer Science
PAKDD
9 April 2006

We propose an intrusion detection algorithm for database intrusion detection using a data mining technique, which takes the sensitivity of the attributes into consideration. Expand
