Detection of transcoded HEVC videos based on in-loop filtering and PU partitioning analyses

作者：

Highlights：

• Transcoding a video would inevitably introduce additional errors.

• The difference in filtering modes would affect the exposure of coding traces.

• A novel algorithm is proposed to detect transcoded HEVC videos.
