ABSTRACT:
A computer-implemented method and apparatus for encoding image signals. According to a preferred embodiment, an image signal is received. A strength S of a variable low-pass filter having a variable strength is selected. The low-pass filter means is applied at strength S to the image signal. The filtered image signal is encoded to provide an encoded bitstream representative of the current image signal.
