Recent research has focused on the image compression algorithms are lossy compression. However, the general algorithm for certain types of images, resulting in poor image quality is usually implemented using a baseline quantization process, especially in the combination of image content. It's a lot different compression image coding based on Wavelet transform technology utilizes signal. A different type of variable image compression algorithms like JPEG, JPEG2000, EZW, SPIHT compression technology which can be used is very important.
