    It is well known that the blocking effect is one of the major drawbacks in the DCT-based compression schemes (such as JPEG) at low bit rates. In this paper, we propose a novel technique to reduce blocking artifacts, which is based on applying a zero-masking to the DCT coefficients of some shifted image data blocks. Some simulation results are presented to show that such a simple method can provide a respectable performance.
