Foveated Image and Video Coding
نویسندگان
چکیده
The human visual system (HVS) is highly space-variant in sampling, coding, processing, and understanding of visual information. The visual sensitivity is highest at the point of fixation and decreases dramatically with distance from the point of fixation. By taking advantage of this phenomenon, foveated image and video coding systems achieve increased compression efficiency by removing considerable high-frequency information redundancy from the regions away from the fixation point without significant loss of the reconstructed image or video quality.

Foveated Vision and Video Quality Evaluation
The using of characteristics of the human visual system (HVS) can significantly improve the efficiency of video coding process. Enhanced coding processes take into account the high spatial variability of HVS in sampling, coding and understanding of visual information. The highest visual sensitivity is at the point of fixation and decreases rapidly with distance from that point. Foveated image a...
متن کاملHuman Visual System Based Scalable Video Coding and Communications
This paper introduces our recent research work on the development of a scalable foveated visual information coding and communication system, which follows two emerging trends in visual communication research. One is to design rate scalable image and video codecs, which allow the extraction of coded visual information at continuously varying bit rates from a single compressed bitstream. The othe...
متن کاملFoveated video compression with optimal rate control
Previously, fovcated video compression algorithms have been proposed which, in certain applications, deliver high-quality video at reduced bit rates by seeking to match the nonuniform sampling of the human retina. We describe such a framework here where foveated video is created by a nonuniform filtering scheme that increases the compressibility of the video stream. We maximize a new foveal vis...

متن کاملAudiovisual focus of attention and its application to Ultra High Definition video compression
Using Focus of Attention (FoA) as a perceptual process in image and video compression belongs to well-known approaches to increase coding efficiency. It has been shown that foveated coding, when compression quality varies across the image according to region of interest, is more efficient than the alternative coding, when all region are compressed in a similar way. However, widespread use of su...
