image compression
Image compression is basically minimizing the size of a graphic files in bytes without degrading the quality of the image to an unacceptable level. The reduction in file size allows more images to be stored in a given amount of disk or memory space. It also reduces the time required for images to be sent over the Internet or downloaded from Web pages. A series of different ways in which image files can be compressed For Internet use include many formats , the two most common compressed graphic image formats are the JPEG format and the GIF format. The JPEG method is more often used for photographs, while the GIF method is commonly used for line art and other images in which geometric shapes are relatively simple. Other techniques for image compression include the use of fractal s and wavelet s. These methods have not gained widespread acceptance for use on the Internet as of this writing. However, both methods offer promise because they offer ...
