【图像压缩】基于香农熵多级阈值实现图像压缩附matlab代码.zip

This is a code for COMPRESSION OF IMAGES. The execution time is independent of the size of the image unlike other image compression techniques. The package contains the following files: Demo.m : A demo file, which can be run directly to view a sample result. compressImage.m : The function that compresses a single channel of the image diffEvolution.m : The function that computes the optimal threshold vectors shannonEntropy.m : The file computes the shannon entropy for of the image for a particular threshold 368016.jpg : A color image taken from Berkeley Segmentation Dataset and Benchmark (BSDS) 368016.png : The gray scale version of the image 368016.jpg Please refer to this paper for further information: Paul, S.; Bandyopadhyay, B., "A novel approach for image compression based on multi-level image thresholding using Shannon Entropy and Differential Evolution," Students' Technology Symposium (TechSym), 2014 IEEE , vol., no., pp.56,61, Feb. 28 2014-March 2 2014, doi: 10.1109/TechSym.2014.6807914 Please cite this reference in your work if you use the codes.
