چکیده
Image processing is a technique to perform operations on an image, with a specific goal to get an enhanced image or to extract some helpful information from it. It is a kind of signal processing in which input is an image and output might be image or characteristics/features associated with that image. These days, image processing is among quickly growing technologies. It forms core research area within engineering and computer science disciplines as well [1]. It is a kind of signal dispensation in which input is image, similar to video frame or photograph and output might be image or characteristics associated with that image. Typically image processing system includes treating images as two dimensional signals while applying effectively set signal processing methods to them. The two sorts of methods utilized for Image Processing are Analog and Digital Image Processing. Analog or visual techniques of image processing can be utilized for the printed versions like printouts and photographs. Digital Processing techniques help in manipulation of the digital images by using computers [2].

متن کاملWeighted universal transform coding: universal image compression with the Karhunen-Loeve transform
We introduce a two-stage universal transform code for image compression. The code combines Karhunen-Lo eve transform coding with weighted universal bit allocation (WUBA) 1] in a two-stage algorithm analogous to the algorithm for weighted universal vector quantization (WUVQ) 2, 3]. The encoder uses a collection of transform / bit allocation pairs rather than a single transform / bit allocation p...
