Reduction of Blocking Effect in Medical Image DCT Transform Compression
Chengbing Zhou · Microcomputer Development · 2005
In this paper, an adaptive approach by modifying little DCT coefficients is proposed to remove the blocking effects in block-based DCT medical compressed images.Simulation results show that the proposed method can significantly reduce the blocking effects with preserving high frequencies of the original images.Furthermore, it requires no complex computation, so it is suitable for real-time applications.
