Contour Approximation for Faster Object Based Transcoding with Higher Perceptual Quality
نویسنده
چکیده
Object aware video rate transcoding can significantly improve the perceptual quality of relatively low bit-rate video. However, precise object detection in arbitrary video scenes is computationally challenging. This paper presents an interesting experimentation with a live eyegaze tracker which suggests that object detection, particularly for perceptual encoding, may not have to be precise. Indeed, a simple approximation can not only reduce the complexity of the detection process, but also result in improved perceptual quality and yield very fast transcoding algorithms.

متن کاملFlock-of-bird Algorithm for Fast Motion Based Object Tracking and Transcoding in Video Streaming
Object based bit allocation enables video coding with high perceptual quality at significantly reduced bit-rate. In this paper, we describe a fast content aware video transcoding technique particularly designed for streaming video. The algorithm can accept an initial high-level description of the expected video objects. The proposed flock-or-bird algorithm then detects and tracks these target s...
متن کاملCompressed Domain Transcoding of MPEG
Current video compression formats optimize for either compression or editing. For example, motion-JPEG (MJPEG) provides excellent random access and moderate overall compression, while MPEG optimizes for compression at the expense of random access. Converting from one format to another, a process called transcoding, is often desirable over the life of a video segment. This paper shows how to tra...
متن کاملSemantic Video Transcoding Using Classes of Relevance
In this work we present a framework for on-the-fly video transcoding that exploits computer vision-based techniques to adapt the Web access to the user requirements. The proposed transcoding approach aims at coping both with user bandwidth and resources capabilities, and with user interests in the video’s content. We propose an object-based semantic transcoding that, according to user-defined c...
متن کاملPerceptual Grouping of Object Contours Survives Saccades
Human observers explore scenes by shifting their gaze from object to object. Before each eye movement, a peripheral glimpse of the next object to be fixated has however already been caught. Here we investigate whether the perceptual organization extracted from such a preview could guide the perceptual analysis of the same object during the next fixation. We observed that participants were indee...
