Modeling the perceptual distortion of dynamic textures and its application in HEVC

In the quest of perceptually optimized video coding, coding textures is representing a challenging case. While a large body of research was put into the perception of static textures, dynamic textures are still not sufficiently explored. In this paper, we focus on short term consistent patches, known as dynamic textures, with a very limited spatial and temporal extent. We estimated the visual distortion due to HEVC compression via subjective testing. The estimated distortion profile per texture was used to optimize the HEVC coding process. Experimental results showed that this technique can offer a high bitrate saving for the same subjective quality.
