We propose a high-performance, nonlinear, loop filter that reduces quantization noise over video frames composed of locally uniform regions (smooth, high frequency, texture, etc.)...
Spread Transform (ST) is a quantization watermarking algorithm in which vectors of the wavelet coefficients of a host work are quantized, using one of two dithered quantizers, to ...
The automatic detection of semantic events in users’ image and video collections is an important technique for content management and retrieval. In this paper we propose a novel...
Error concealment is very important for video communication as an application-layer error control mechanism which can be used independently of the underlying communication infrast...
For the low bit rate (LBR) video communications, LBR transcoding is performed by the transcoder to match the network bandwidth and the performance of the client. One of typical tr...
