Abstract
Seismic blind zones (weak or incoherent reflections) are an important source of mistakes for automatic 2D/3D interpretation softwares, and their detection would save these softwares a substantial computation time. To isolate these blind zones, we apply a recent image processing technique, the SNAKE method, traditionally used for edge detection, and we adapt it to the particular case of seismic images, to find smoothly shaped blind zones . After a description of the SNAKE method, we apply it to our problem, and illustrate the method on a 2D seismic section.
