METHOD FOR DETECTING CONTOURS IN IMAGING, AND LOCAL ESTIMATION OF THEIR PARAMETERS, IN A SPACE OF AT LEAST THREE DIMENSIONS, AND DEVICE FOR IMPLEMENTING SAID METHOD

摘要

THIS PROCESS COVERS IMAGE PROCESSING. ANY HYPERCONTOUR IS MODELIZED LOCALLY BY A PORTION OF HYPERSURFACE, FOR EXAMPLE A PLAN WHOSE PARAMETERS R CAN TAKE PREDETERMINED VALUE SETS. FOR EACH POINT OF THE IMAGE, THE METHOD CONSISTS OF: / P P -CALCULATING PRODUCTS OF CONVOLUTION LG AND LG, FOR I1 AS, OR L AND L ARE SQUARE MATRIXS FORMED RESPECTIVELY BY LUMINANCE VALUES OF THE CURRENT IMAGE AND THE NEXT IMAGE; OR G AND G ARE DIES FOR DETECTING A HYPERCONTOUR MODELISABLE BY A HYPERSURFACE GOING THROUGH THE CURRENT POINT AND HAVING R FOR PARAMETER VALUES; / P P -CALCULATING THE VR VALUES OF A GENERALIZED REALITY REPORT: / P P VRLGLGPOUR I1 AS; / P P -DETERMINATE AMONG THE VALUES VR THE VALUE VRS THAT IS MAXIMUM AND COMPARE IT WITH A VALUE FIXED L / P P -CONCLURE QU THERE IS NO HYPERCONTOUR THROUGH THE CURRENT POINT IF VRS L, OR CONCLUDE THAT THERE IS A HYPERCONTOUR, MODELISABLE BY A PORTION OF HYPERSURFACE HAVING PARAMETER VALUES CORRESPONDING TO VRS IF VRS L. / P P APPLICATION TO THE ESTIMATION OF THE MOVEMENT OF A CONTOUR ELEMENT, TO THE DETERMINATION OF A TRI-DIMENSIONAL CONTOUR.
