Their large size entails two problems one is of the large bandwidth requirement and other is of more time required for uploading and downloading through internet. To combat these problems images are compressed. Block based DCT is used to compress the still images and video sequences because of its energy compaction property but bdct yields the blocking artifacts in images. To remove blocking artifacts various de blocking techniques have been devised and a comparative analysis of these post processing spatial domain techniques have been presented in this paper.
