Abstract

Digital cinema is a very challenging field that will allow providing cinema material with a very high quality level. In the last years the key role of the Human Visual System (HVS) in the final perceived quality of the compressed images, becomes an undeniable reality. Therefore, it is natural to take advantage of the recent knowledge of human visual perception and models in an image compression system. Thus, in this paper we propose a reproducible technique for improving the perceptual JPEG 2000 image compression quality with a digital cinema profile. This technique consists of two main parts: a laboratory evaluation of a HVS model by the Contrast Sensitivity function (CSF), and the implementation of visual weightings for the JPEG 2000 scheme, using the evaluated HVS model, in the spatial Fourier domain of the wavelet decomposition sub-bands.
