Abstract

The invention concerns a method in an optoelectronic image processing for monitoring and tracking punctual targets, which consists in providing a quantization of a level of complexity of the local background on which a target is detected in an image, to adapt the criteria for associating blips with tracks based on said complexity level. Said quantization is based on a segmentation of the image into zones of homogeneous radiometric characteristics. The integration of the complexity level of the local background on which a punctual target is detected enables the hypothetical tracks for which the blips detected are highly contrasted to be more rapidly validated. Further, it enables phantom blips to be detected, exclusively for monitoring the validated tracks, by locally lowering the blip detection threshold in a zone of the complex image in which the target should be located.
