Abstract: With the computer and digital products technology continues to improve, people of various digital image storage requirements increasing, so the image compression is necessary. Image compression, allows people to use less space to store a large number of images, especially in network communication, it plays a very important role. There are many image compression methods, can attribute the image itself, using different types of compression to achieve the best image compression.
This design mostly using run-length coding method for lossless compression of binary images, do an effective binary image compress, and on the compressed picture to decompression, lossless reduction of the image.
This design is compiled using Delphi7.0, the main function is to be processed into the color pictures, to image binarization, making the image suitable for compression, and through run-length encoding compression algorithm for lossless image compression. For comparison of compression efficiency, image processing can be carried out through the gray-scale processing, compression algorithm to compare the adaptability. The software interface is simple, easy to use, and fully reflects the binary image compression efficiency.
