An original method for an automatic detection of contoursin difficult images is proposed. This method is basedon a tight cooperation between a multi-resolution neuralnetwork and a hidden Markov model-enhanced dynamicprogramming procedure. This new method is able to overcomethe three major drawbacks of the "standard" activecontours: initialization dependancy, exclusive use of localinformation and occlusion sensitivity. The driving idea isto introduce high-order a priori information in each step ofthe system. An application to the automatic detection of theleft ventricle in digital X-ray images is proposed.
