This paper presents a new adaptive scheme to reduce the computation energy of the discrete cosine transform (DCT) architecture for image/video coding. The scheme employs the noise ...
A scene-adaptive rate control algorithm with an enhanced frame skipping is proposed for low bit rate video coding. Most existing rate control algorithms for low bit rate video focu...
This is a contribution for very low bit rate video coding in real-time and software only on computers of PC class. It is based on frame replenishment with block coding using mean-...
The modified Differential Pulse Coded Modulation (DPCM) codec with multi-rate processing has been shown to able to code source with monotonically decreasing spectrum efficiently a...
Abstract. In many rate control models, a uniform weighted distortion has been assumed; that is, the DCT coefficients of the motioncompensation difference frames (residues) conform...
