Abstract
We propose a fast partial decoding algorithm for content access to MPEG compressed videos, where full decompression is not necessarily required, such as compressed video browsing, content analysis, and specific pattern search. The proposed decoding bypasses the inverse DCT via an approximation process to extract average pixels directly from compressed DCT coefficients. Although such extracted pixels may incur differences compared with their fully decompressed counterparts, extensive experiments show that such partially decoded video frames preserve their content very well and achieve reasonable perceptual quality in terms of visual inspections.
