In search of a human visual quality criterion for image data compression

Primary tabs

Macq, Benoît [UCL] Delogne, Paul [UCL]

Transmission of digital pictures is characterized by the large amount of data and the high correlation of the sources. This is the reason why decorrelative picture coding is generally processed before any digital picture transmission. In order to reach acceptable bit rates, an information limitation is, furthermore, unavoidable. The compression ratio of the coding scheme is fixed by an economical trade-off between the codec complexity and the transmission costs. This optimum is obviously also fixed by the picture quality to be reached. Presently, one of the main problems in image data compression is the search for a human visual quality criterion. Human visual quality criteria for digital TV pictures are described. It is shown how to use such quality criteria in order to optimize transform coding schemes quantization.
