METHOD FOR ENCODING AND DECODING INTERLEAVE HIGH-RESOLUTION AND PROGRESSIVE LOW-RESOLUTION IMAGES

摘要

The inventive method consists in encoding a low-resolution image (2) for delivering an encoded low-resolution image, in decoding the low-resolution image (3) for delivering a reconstructed low-resolution image, in upsampling (4) the reconstructed image for delivering a prediction image, in separating (5) a reconstructed upsampled image into even and odd prediction frames, in deinterleaving (6) a high-resolution image for delivering even and odd high-resolution frames, in encoding (7, 8) the even or odd high-resolution frame by computing the difference between the high-resolution frame and the prediction frame of the same parity in such a way that an encodable residue is available.
