摘要

The method involves filtering a set of initial samples by applying a high pass filter according to a set of geometric orientations to provide a set of filtered samples, where the high pass filter is applied by perusing the samples according to the dimension of a digital image such as still image. The set of filtered samples is selected by implementing a predetermined criterion such as minimum coding cost, to constitute an intermediate sub band. A single sub-sampling of the intermediate sub-band is filtered by perusing the intermediate sub-band in another dimension of the image. Independent claims are also included for the following: (1) a method for decoding a multidimensional digital signal (2) a device for coding a multidimensional digital signal (3) a device for decoding a multidimensional digital signal (4) a computer program comprising a set of instruction for performing a multidimensional digital signal filtering method.
