Abstract

Procédé de surveillance de l’application d’une transformation spatiale d’image(s) source(s), programme d’ordinateur et dispositif électronique associés L’invention concerne un procédé (26) de surveillance de l’application d’une transformation spatiale d’image(s) source(s), comprenant les étapes suivantes : - formation et insertion (30) de motifs concentriques distincts à des positions de chaque image source, par association à chaque groupe d’au moins un pixel de chaque image source, d’un attribut de N bits, un motif concentrique correspondant à la combinaison unique de valeurs d’attributs distinctes, l’une étant associée à une région centrale dudit motif et une autre associée à une région périphérique distincte de ladite région centrale, - application (32) de ladite transformation spatiale délivrant une image spatialement transformée, - extraction (34), au sein de ladite image spatialement transformée, de la position de chaque motif transformé spatialement, par détection d’une transition entre lesdites valeurs d’attributs, - surveillance (36) par comparaison de ladite position de chaque motif transformé spatialement à une référence correspondant à l’application valide de ladite transformation spatiale. Figure pour l'abrégé : figure 4Method for monitoring the application of a spatial transformation of source image(s), computer program and associated electronic device The invention relates to a method (26) for monitoring the application of a transformation spatial source image(s), comprising the following steps: - formation and insertion (30) of distinct concentric patterns at positions of each source image, by association with each group of at least one pixel of each image source, of an N-bit attribute, a concentric pattern corresponding to the unique combination of distinct attribute values, one being associated with a central region of said pattern and another associated with a peripheral region distinct from said central region, - application (32) of said spatial transformation delivering a spatially transformed image, - extraction (34), within said spatially transformed image, of the position of each spatially transformed pattern, by detection of a transition between said attribute values , - monitoring (36) by comparing said position of each spatially transformed pattern to a reference corresponding to the valid application of said spatial transformation.
