Venue: Regency Ballroom, Hyatt Regency Kolkata.
The tutorial program was inaugurated by Prof. S.K.Pal, FIEEE, of Indian Statistical Institute of Kolkata. In his inaugural address, Prof. Pal outlined the issues related to wavelet transform and fractal synthesis with particular reference to signal processing and image analysis.
The entire tutorial program was divided into two sessions. The pre-lunch session was on 'Wavelet Transform' and the post-lunch session was on 'Fractal Analysis'. The tutorial sessions were chaired by Prof. N.Chatterjee, former Chairman of Power Engineering Chapter of IEEE Calcutta Section.
In the first session on wavelet transform, there were two presentations. The first one was on 'Wavelet Transform: Fundamentals and Some Applications' by Prof. S. Chakravorti of Electrical Engineering Department of Jadavpur University. In his talk Prof. Chakravorti discussed the features of continuous wavelet transform (CWT). He also discussed the advantages and disadvantages of CWT vis-à-vis other transforms, such as Fourier Transform. The second talk was on 'Wavelets: Application to Texture based Image Analysis' by Prof. M.K.Kundu of Machine Intelligence Unit of Indian Statistical Institute of Kolkata. In his presentation Prof. Kundu discussed in details the discrete wavelet transform, wavelet packets and also M-band wavelet transform. His presentation included experimental results on real life data using various forms of discrete wavelet transform. Application of M-band wavelet in the analysis of printed document containing both text and graphical image was also highlighted.
In the post-lunch session on fractal analysis, there were two lectures, too. The first lecture was given by Prof. A.K. Mandal of Electronics and Tele-communications Engg Dept of Jadavpur University on 'Concept of Fractal and Fractal Structures'. In his talk Prof. Mandal explained in details the underlying principles of fractal synthesis. He also presented a thorough insight into the modeling of fractals using Iterated Function Systems (IFS) that are developed with the help of contraction maps. This talk was followed by another one on 'Fractal based Image Compression' by Dr. C.A. Murthy of Machine Intelligence Unit of Indian Statistical Institute of Kolkata. Dr. Murthy dwelt upon lossless as well as lossy compression of images. In this context he discussed how generalized collage theorem for Partitioned Iterated Function Systems (PIFS) is used in fractal based image compression schemes. He concluded by showing how Genetic Algorithm when coupled to fractal analysis can provide excellent compression ratios for different images.
There were more than 110 registered participants in this tutorial program from various educational institutes, industries and research organizations, out of which about 35 were student participants. A summary preprint of all the four presentations were also published in this occasion.
