Detection of Double Compression in HEVC Videos Containing B-Frames
This study proposes a method to detect double compression in H.265/HEVC videos containing B-frames, a scenario underexplored in previous research. The method extracts frame-level encoding features—including frame type, coding unit (CU) size, quantization

Fast Rate Estimation for RDO Mode Decision in HEVC
The latter-day H.265/HEVC video compression standard is able to provide two-times higher compression efficiency compared to the current industrial standard, H.264/AVC. However, coding complexity also increased.

Impact Analysis of Baseband Quantizer on Coding Efficiency for HDR Video
Digitally acquired high dynamic range (HDR) video baseband signal can take 10 to 12 bits per color channel. It is economically important to be able to reuse the legacy 8 or 10-bit video codecs to efficiently compress the HDR video.

H.265/HEVC frame-level bitrate allocation algorithm considering video content
In order to guarantee the consistency between the coded bits and target bits,a frame-level bitrate allocation al-gorithm considering the content feature was proposed for H.265/HEVC codec.The main factors to affect the output bi-trate were first discussed
