Abstract :
A method of local contrast enhancement in space frequency domain together with a segmentation method for medical 3D-CT image data by active contours is presented. The purpose of the project is to define tumor volumes for irradiation in cancer therapy. For a better performance of the contouring algorithm the image is primarily processed by a nonlinear operator in space frequency domain for local contrast enhancement.
