A primary class of the image inpainting technique is to build up a partial differential equation

and solve it with some iterative method. One of the most representative inpainting algorithms is BSCB mode.l Because BSCB model’s main drawback is slow calculation

this paper proposes selective adaptive interpolation algorithm based on diffusivity function. The experimental results show that this method is easier to implement and faster in computation than BSCB model

and improves the inpainting effects.
