Abstract :
This paper presents an implementation of nonlinear anisotropic filtering, using resistive fuse circuitry, on the 64??64 cell MIPA4k mixed mode image processor array. Anisotropic filtering can be used to implement very effective edge preserving noise filtering, image segmentation as well as direct edge detection. The MIPA4k processor cell is capable of performing globally or locally controlled anisotropic diffusion in two ways, either for resistive or capacitive input configurations, resulting in different diffusion networks and performance. The array cells can also directly extract edge information from the resistive fuse circuitry. Measured examples of the nonlinear anisotropic filtering and edge extraction on the MIPA4k processor array are presented.
