Patent ID: 8711945

Claim:
A method of coding a digital image which includes plural macroblocks of which one macroblock is designated as a current macroblock, the method comprising: a step of motion estimation applied to said current macroblock and to at least one reference image to obtain one or more first macroblock predictors for a current block in each reference image, a step of obtaining a second macroblock predictor for the current block from a spatial scalability level lower than a spatial scalability level of the current macroblock, a step of transforming, from a spatial domain to a frequency domain, at least one of the one or more first macroblock predictors, a step of predicting in the frequency domain at least one low spatial frequency coefficient on the basis of the second macroblock predictor and a step of predicting in the frequency domain at least one high spatial frequency coefficient on the basis of at least one high frequency coefficient of the at least one transformed first macroblock predictor.
