Title: METHODS FOR SPATIALLY SCALABLE CODING AND DECODING AND CORRESPONDING DEVICES
Abstract:
A spatially scalable coding device, in a video encoder, of a high resolution image from a low resolution image, said images being represented in a non linear color space, is described. The coding method comprises a first transformation step (14) in a linear color space of at least one block of the low resolution image, an upsampling step (16) of the at least one transformed block, a second transformation step (18) in the non linear color space of the at least one upsampled block and a coding step (20) of at least one block of the high resolution image from the at least one transformed upsampled block.
