Rate-Distortion-Preserving Forensic Watermarking Using Quantization Parameter Variation
IEEE Access, 2020 Watermarking enables the identification of digital pirates that illegally redistribute copyright-protected videos. One of the main challenges is for the watermark to be imperceptible, while not increasing the video bit rate.

Tracking-Optimized Quantization for H.264 Compression in Transportation Video Surveillance Applications [PDF]
, 2011 We propose a tracking-aware system that removes video components of low tracking interest and optimizes the quantization during compression of frequency coefficients, particularly those that most influence trackers, significantly reducing bitrate while ...
