METHOD AND SYSTEM FOR IMAGE SCALING BASED ON EDGE SELF-ADAPTATION

摘要

Provided in the present invention are a method and system for image scaling based on edge self-adaptation. The method comprises: determining the positions of pixels to be interpolated in an original image; calculating an edge direction and a strong-edge probability of the pixels to be interpolated; if the strong-edge probability of the pixels to be interpolated is not equal to zero, then interpolating by utilizing an edge interpolation method on the basis of the edge direction; if the strong-edge probability of the pixels to be interpolated is zero, then interpolating on the basis of a non-edge interpolation method; making the strong-edge probability and a complementary probability of the strong-edge probability respectively as an edge interpolation fusing weight and a non-edge interpolation fusing weight, and performing a weighted fusion on an interpolation result produced by the edge interpolation method and that by the non-edge interpolation method to produce a final interpolated image. The method of the present invention allows image interpolation in any arbitrary edge direction and production of a clear and unpixelated image when scaled.
