Summary In this paper investigation is made of the. use of entropic methods to identify smooth image blocks in order to filter the reconstructed image of block based transform coded images. We know that blocking artefact is Visually more prominent in the smooth region of a block rather than in the textured region. The entropic methods are employed to distinguish between smooth and textured blocks in a reconstructed image. The linear filtering is then carried out on the smooth region of the image to reduce the blocking artefact. The en tropic criteria investigated in this paper are: Shannon's (Logarithmic) Entropy, Exponential Entropy, and Quadratic Entropy.
