VIDEO AND/OR IMAGE DATA PROCESSING WITH DETERMINATION OF REPRESENTATION FUNCTIONS

摘要

The invention relates to video and/or image data processing with determination of representation functions. According to the invention, one device (DT) is dedicated to processing n-dimensional input data that are representative of an image or a sequence of images with n dimensions corresponding to n directions, whereby n = 2. The invention comprises processing means (MT) which, upon receipt of input data, perform the following steps consisting in: (i) defining one or more connecting n-dimensional domains having complementary shapes which are defined by position data and containing input data; (ii) subsequently, for each n-dimensional domain, determining a representation function that is representative of the set of input data contained therein and constructed from basic functions selected from at least one database of basic functions and respectively associated with selected coefficients, whereby said representation functions can be connected in pairs at least; and (iii) transforming at least some of the coefficients of at least one of the representation functions into representation data which, together with the associated position data, define output data that are representative of the input data.
