Digital filters are pipelined to achieve high sampling rates. FIR filters can be pipelined in a fairly straight forward manner. However, IIR filters are pipelined by the “loop unfolding” technique which calls for larger silicon area. This thesis is an attempt to tackle this problem. text/html 2010-12-24T10:35:19+00:00 http://www.ee.iitm.ac.in/vlsi/people/srini/ms/ms_kumud?rev=1293186919&do=diff Algorithmic implementation and architectural design of a modified Watershed Algorithm for image segmentation applications By Kumud Prakash Gupta Abstract Keywords: Watershed Transform, MPEG 4, FIFO, Mathematical Morphology, Segmentation The rapid advances in computer hardware, software and communication systems have opened the doors for the new cutting edge technology of multimedia communications.

Abstract Image processing by far has not benefited as much as speech and audio processing from the development of Digital Signal Processors (DSPs). This is because most existing DSP architectures are optimised to handle one dimensional data efficiently. Hence, most programmers tend to rely on factorisation techniques to decompose the two dimensional data array into separable … text/html 2010-12-24T10:35:19+00:00 http://www.ee.iitm.ac.in/vlsi/people/srini/ms/ms_srikar?rev=1293186919&do=diff Efficient architectures for Lifting based forward and inverse Discrete Wavelet Transforms for still image compression.
