الملخص

Image segmentation by active contours is a method to locate the boundaries ofobject, using a curve that deforms by minimization of energies. In this memory, wepropose a parallel approach for fast object tracking in medical images sequence. Theproposed approach defines three Agents: The first uses a pyramidal multiresolutionanalysis to decompose the images of the sequence in multiple resolutions. The secondagent detects the object in low–resolution images by parametric active contours. Thethird agent realizes the projection of the contours detected in low-resolution images tohigh-resolution images. Our approach was tested using three sequence types:synthetic, biological and echocardiographic, the obtained results are encouraging.Key
