Abstract
The invention relates to a method for the fragmentation (F) of images (14i) into homogeneous regions (Ri), this fragmentation (F) using iterative merges of fragments Fi and Fj which are as similar as possible according to at least one selection parameter, this similarity being evaluated by a product A*B of two factors A and B, A being consistent with a number of pixels and B being consistent with the selection parameter(s). According to the invention a merge is performed when the product A*B*C is less than a threshold consistent with the selection parameter, C being a factor consistent with the inverse of a number of pixels.

Method for the fragmentation (F) of images (14i) into homogeneous regions (Ri), this fragmentation (F) using iterative merges of fragments Fi and Fj, among at least 3 fragments in the image, which are as similar as possible according to at least one selection parameter, this similarity being evaluated by a product A*B of two factors A and B, A being consistent with a number of pixels relating to the fragments Fi and Fj and B being consistent with the selection parameter(s), characterized in that a merge is performed when the product A*B*C is less than a threshold consistent with the selection parameters, C being the inverse of a number of pixels per fragment, in the image.
