Contour Approximation can Lead to Faster Object Based Transcoding with Higher Perceptual Quality
Javed Khan, Oleg V. Komogortsev · 2003
Object aware video rate transcoding can significantly improvement the perceptual quality of relatively low bit-rate video. However, precise object detection in arbitrary video scene is computationally extremely challenging. This paper present an interesting experimentation with live eye-gaze-tracker which suggests that object detection particularly for perceptual encoding may not have to be precise. Indeed, intelligent approximation can not only reduce the complexity of the detection process, but also result in improved perceptual quality and yield very fast transcoding algorithms. Key words: transcoding, perceptual encoding. 2
