Este artigo propõe um algoritmo de codificação unificado para a compressão sem e quase sem perdas de imagens estáticas coloridas. O esquema de codificação de imagem em cores unificado proposto pode controlar a relação sinal-ruído de pico (PSNR) da imagem reconstruída enquanto o nível de distorção no plano RGB é suprimido dentro de uma magnitude predefinida. Para controlar o PSNR, o nível de distorção é alterado de forma adaptativa em cada pixel. Um quantizador adaptativo para controlar a distorção é concebido com base em critérios psicovisuais. Por fim, experimentos em imagens de Super Alta Definição (SHD) mostram a eficácia do algoritmo proposto.

Abstract: This paper proposes a unified coding algorithm for the lossless and near-lossless compression of still color images. The proposed unified color image coding scheme can control the Peak Signal-to-Noise Ratio (PSNR) of the reconstructed image while the level of distortion on the RGB plane is suppressed to within a preset magnitude. In order to control the PSNR, the distortion level is adaptively changed at each pixel. An adaptive quantizer to control the distortion is designed on the basis of psychovisual criteria. Finally, experiments on Super High Definition (SHD) images show the effectiveness of the proposed algorithm.
