Abstract
The thumbnail pictures can be generated from the frequency data, which is called H.264 advanced video coding (H.264/AVC) bitstreams, directly without inverse transform process. However, it makes some error caused by rounding of the floating point operation and it will be propagated to neighbor blocks. In this paper, we propose an error compensation method for fast thumbnail generation considering error propagation. It determines the block-based compensation value using the error distribution of intra prediction mode and gives the weighting factor to cover the error propagation.
