[2D Graphic] wavecompression DL : 0: The following implementation steps have been made for the devised algorithm, which is based on 2D-wavelet. 1. Reading an image of either gray scale or RGB image. 2. Converting the image into grayscale if the image is RGB. 3. Decomposition of images using wavelets for the level N. 4. Selecting and assigning a wavelet for compression. 5. Generating threshold coefficients using Birge-Massart strategy. 6. Performing the image compression using wavelets. 7. Computing and displaying the results such as compressed image, retained energy and Zero coefficients. 8. Decompression the image based on the wavelet decomposition structure. 9. Plotting the reconstructed image. 10. Computing and displaying the size of original image, compressed image and decompressed image.

[matlab] VcDemo DL : 0: Video Compression using Content-Based Motion Compensation --------------------------------------------------------- This demo Requires MATLAB (and the Image Processing Toolbox) Tested on MATLAB 7.0 (R14). Run one of the following three MATLAB scripts: * DemoEncodeCrowd (encodes some frames from the "crowd" sequence) * DemoDecodeCrowd (decodes the previously encoded frames) * DemoDecode (generic decoder) Note that the encoding script can be modified so that the user can specify the values of a number of input variables. This code is VERY SLOW. A lot could be done to speed it up! In MS-Windows, use the YUV file player to view YUV files. ----------------------------------------- Based on the PhD Research of Marc Servais www.ee.surrey.ac.uk/CVSSP/VMRG/hdtv/ -Video Compression using Content-Based Motion Compensation --------------------------------------------------------- This demo Requires MATLAB (and the Image Processing Toolbox) Tested on MATLAB 7.0 (R14).
