Estimating and transmitting regular parameters for reducing blocking artifacts

High compression ratios for both still images and sequences of images are usually achieved hy quantizing tile block discrete cosine transform (BDCT) coefficients of the intensity or displaced frame different values, This block based processing and quantization yields images that exhibit annoying blocking artifacts, In this paper, We propose a method based on the hierarchical Bayesian approach for tile reconstruction of BDCT compressed images and the estimation of tile related parameters both at the coder and decoder, We examine how to combine the parameters estimated at the coder and decoder and test tile method on real images.
