摘要
We study a quasi-linear system arising in image segmentation in order to determine the minimum of the Mumford-Shah functional. We prove the existence of a solution for a larger class of systems including the previous one. The recursive method used in the proof produces as well an efficient algorithm that can be easily implemented in connection for example with finite element techniques. Results of some numerical experiments are also discussed.
