摘要
Many state of the art methods for video compression rely on the Discrete Cosine Transform (DCT) and the quantization of its coefficients. Here we present a video deblocking system which is based on the properties of the DCT. Hence it is suitable for MPEG-2 compressed videos, since the MPEG-2 standard belongs to this class of compression formats. The system carries out an online analysis of the video in order to adapt its operation to the characteristics of the incoming video frames. Experiments with benchmark real videos are shown, which demonstrate the performance of our proposal both in quantitative and qualitative terms.
