Method of embedding of an image with a color transform

摘要

The method comprises the generation of a deteriorated image associated with a first bit rate (R1) and of a deteriorated color transform associated with a second bit rate (R2), an evaluation of a first distortion (dE1) by comparison of the image with a first test image obtained by the application of the color transform to the deteriorated image, and of a second distortion (dE2) by comparison of the image with a second test image obtained by the application of the deteriorated color transform to the image, and the determination of a final conjoint bit rate (R f ) associated with a best trade-off between a conjoint bit rate (R = R1 + R2) and a global distortion (dE = dE1+DE2). The optimized deteriorated image and the optimized deteriorated color transform are then embedded based on this conjoint bit rate (R f ).
