A new approach to ROI based image compression using simple sliding window spatial filter

By reducing the file size, the number of images stored in the given amount of hard disk can be increased and the time required to send images over the internet has been reduced. Image compression is the common and adaptive method used for reducing all the chunks in our day to day life. There are many existing techniques and protypes available for compression. This paper deals with the special concepts on image compression using simple sliding window spatial filter or mean filter. The desired region can be selected using ROI from the image which can be processed for further compression of images. The proposed method uses DCT followed by the suitable encoding techniques. Various combinations of compression applied to come across the best one.
