The Rate Constrained Block Matching Algorithm, (RC-BMA), introduced in this paper jointly minimizes DFD (Displaced Frame Diierence) variance and entropy or conditional entropy of motion vectors for determining the motion vectors in low rate video coding applications where the contribution of the motion vector rate to the overall coding rate might be signiicant. The motion vector rate vs. DFD va...

Background & Aims: One of the important aims of quantitative cardiac image processing is the clarification of myocardial motions in order to derive biomechanical behavior of the heart in the disease condition. In this study we presented a computerized analysis method for detecting the instantaneous myocardial changes by using 2D echocardiography images. Methods: The analysis was performed on th...

This paper proposes a novel frame rate up-conversion(FRUC) algorithm based on morphing. In order to obtain high quality interpolated frames, the proposed algorithm follows prewarping in view morphing to find more accurate matching points, and use three steps to gain dense matching points: coarse matching, error match rejecting and points densifying. Unlike conventional motion compensated interp...

With the register detection problem, the color textile image segmentation algorithm based on MeanShift and the block matching algorithm based on Harris corner detection were proposed. The extended MeanShift algorithm was used to segment the textile image, and then different color regions were extracted from the segmented standard image; then the feature points were detected by Harris operator, ...

This paper propose a new block matching algorithm for motion estimation. Four different block matching algorithms using for motion estimation are evaluated where no of computation to find out best match and peak signal to noise ratio (PSNR) are used to find out most optimal algorithm. Four different block matching algorithm are implemented in MATLAB. Each algorithm is evaluated using PSNR and s...
