Abstract
The present invention concerns a method and device (10, 20) for the processing, in particular coding or decoding or more generally compression or decompression, of a video sequence (110) consisting of a series of digital images (401 to 407) comprising a current image (401) to process. The method comprises the steps consisting of: —generating (511, 603, 720, 812) a first reconstruction of a first image (402 to 404) in the sequence, so as to obtain a first reference image (517, 610, 717, 810); —generating (519, 612, 720, 812) a second reconstruction of the first image (402 to 404) different from the first reconstruction, so as to obtain a second reference image (518, 611, 718, 811); and—predicting (505, 606, 705, 806) at least part of said current image (401) from at least one reference image selected from the generated first and second reference images (516, 608, 716, 808).
