Abstract :
This paper presents a fast thumbnail extraction method for HEVC. The proposed method reconstructs only the 4×4 boundary pixels requested for a thumbnail image. We found that the proposed partial decoding method reduced decoding time significantly compared to the conventional method. In addition, the visual quality of the obtained thumbnail images was nearly identical to that of thumbnail images extracted after a full decoding process.
