Expert JPEG Application : WWW JPEG coded images are used in many applications with graphical functions, for example in Web browsers. Here, the images are transferred in coded form and are represented in decoded form. Image Compression: Preparation: In the first step of an image compression process the images are prepared for the actual processing. Image Preparation in JPEG (componentes): Components at the image preparing state of JPEG may be assigned, for example, to the different colours in RGB (red, green, blue), YIQ or YUV signals, for example. A gray-scale image will, in most cases, consist of a single component. An RGB colour representation has three components with the same number of lines and the same number of columns.
Image Preparation in JPEG: In the first step of JPEG the image is represented in n (0 < n < 256) components. Each component consists of an arry of pixels.
