Abstract
Convolution mask is a basic and useful tool for image processing allowing edge detection, noise cleaning, texture extraction . . . Nevertheless, such operators are time consuming in the two following cases : when the mask is large (until 64*64 for texture or correlation extraction ) and when the convolution is iterated. A parallel architecture is efficient in order to limit the processing time but necessitates an overlapping (2n lines and 2n columns) of the fields affected to the different processors. Such an overlapping allows a limited number of iterations ( n in the case of a 3*3 mask) . Thus, if we need more than n iterations, a refreshment of the memory is done in order to process only " true " radiometries.
