 We are pleased to invite you to the following seminar: On Cardiac Signal analysis, by Prof. Bidyut Baran Chaudhuri,
Indian Statistical Institute, Kolkata. The seminar is jointly organized
by School of Computing (SOC), NUS and Pattern Recognition and Machine
Intelligence Association (PREMIA).
Title: On Cardiac Signal analysis
Speaker: Professor Bidyut Baran Chaudhuri, Indian Statistical Institute, Kolkata
Date: 21 November Friday
Time: 2.00 pm - 3.00 pm
Venue: MR6 (AS6-05-10), School of Computing, NUS
Chaired by Prof. Tan Chew Lim (tancl@comp.nus.edu.sg)
Abstract:
Two major types of non-invasive cardiac signals are ECG and cardiac MRI images. A large body of work exists on ECG signal analysis. We start on basics of ECG signaling and introduce Rough set theory based approach for pattern classification, especially for some common heart ailments. Experimental results on normal and diseased ECG records are presented. In the second part of the talk we consider the problem of following beating heart boundary in the sequence of MRI images. For that purpose, some image preprocessing followed by level set based active contour model has been utilized. A demonstration of the border following is also given.
Biodata:
Professor B. B. Chaudhuri received his Ph. D. Degree from Indian Institute of Technology, Kanpur in 1980 and worked as postdoc fellow at Queen's University, U. K. during 1981-82. He joined Indian Statistical Institute in 1978 where currently he is the Head of Computer Vision and Pattern Recognition Unit, ISI, Kolkata. His research interests include Pattern Recognition, Image Processing, Computer Vision, Natural Language Processing (NLP), Information retrieval, Speech processing, Digital Document Processing and OCR. He pioneered the Indian language Bharati Braille system for the blind, a Bangla speech synthesis system and the first workable OCR for Bangla, Devnagari, Assamese and Oriya scripts. Also, a robust Indian language spell-checker, morphological processor, named entity and multi-word expression detector were pioneered by him. He has published about 325 research papers in international journals, proceedings and edited volumes. Also, he has authored five books entitled Two Tone Image Processing and Recognition (Wiley Eastern, 1993), Object Oriented Programming: Fundamentals and Applications (Prentice Hall, 1998), Computer and Software Technology Dictionary (Ananda Publishers, 2002), Digital Document Processing (B B Chaudhuri Ed. Springer-Verlag, London 2007), Matlab Programming (Prentice Hall, 2007). He received Leverhulme fellowship award (1981-82), J. C. Bose Memorial Award (1986), M. N. Saha Memorial Award (twice in 1989 and 1991), Homi Bhabha Fellowship award (1992), Dr. Vikram Sarabhai Research Award (1995), C. Achuta Menon Prize (1996) , Homi Bhabha Award: Applied Sciences (2003) Ram Lal Wadhwa Gold Medal (2005) and Jawaharlal Nehru Fellowship (2004-2006). He is a Fellow of International Association of Pattern Recognition (IAPR), IEEE, Indian National Science Academy, National Academy of Sciences, Institution of Electronics and Telecommunication Engineering, and Indian National Academy of Engineering. He is an associate editor of Pattern Recognition, VIVEK, International Journal of Pattern Recognition and Artificial Intelligence, International journal of Computer Vision, International Journal of Document Analysis and Recognition and IETE Technical Review.
