Abstract
The method comprises the generation of a deteriorated image associated with a first bit rate and of a deteriorated color transform associated with a second bit rate, an evaluation of a first distortion 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 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 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.
