Adaptive image coding with perceptual distortion control
This paper presents a discrete cosine transform (DCT)-based locally adaptive perceptual image coder, which discriminates between image components based on their perceptual relevanc...

Additive vector decoding of transform coded images
—In a standard transform coding scheme of images or video, the decoder can be implemented by a table-lookup technique without the explicit use of an inverse transformation. In th...

Joint Utilization of Fixed and Variable-Length Codes for Improving Synchronization Immunity for Image Transmission
Robust transmission of images is achieved by using xed and variable-length coding together without much loss in compression e ciency. The probability distribution function of a DC...

Embedded multiple description coding for progressive image transmission over unreliable channels
A multiple description scalar quantization (MDSQ) based coding system can be regarded as a source coder (quantizer) followed by a channel coder, i.e. the combination of index and ...
