dc.description.abstract | In this paper we propose a fast adaptive image restoration filter using DCT-based block-classification for reducing block artifact in compressed images. More specifically, edge direction of each block is classified by using the DCT coefficients, and the adaptive CLS filter with corresponding direction is used for smoothing discontinuity between blocks. For real-time application, the proposed restoration filter can be realized in the form of a truncated FIR filter, which is suitable for postprocessing reconstructed images in HDTV, DVD, or video conferencing systems. | - |
