The paper aims at selecting an efficient variable block size mode in H.264 video coding standard for better compression performance. This standard allows video frames to be partitioned into variable block sizes such that blocks containing highly detailed motion are represented using small block sizes and the rest using large block sizes. New techniques for(More)
The inclusion of the Discrete Wavelet Transform in the JPEG-2000 standard has added impetus to the research of hardware architectures for the two-dimensional wavelet transform. In this paper, a VLSI architecture for performing the symmetrically extended two-dimensional transform is presented. This architecture conforms to the JPEG-2000 standard and is(More)
This paper presents a modified structure based on cascaded integrator comb (CIC) filters and polynomial interpolation to perform arbitrary sample rate alterations. Incorporating CIC compensation filter within the polynomial interpolator has obviated programmable filter typically used in the process. It has also been shown that a maximum passband ripple of(More)
A new recursive-search based motion estimation algorithm has been proposed that uses only a maximum of seven candidate motion vectors. The coding quality in terms of signal to noise ratio and compression is quite close to full search motion estimator. The algorithm is extremely light with respect to the computational load. Proposed algorithm improves upon(More)
