Triangle based Image Magnification

Abstract

There was presented image magnification method based on new pixels intensity calculation from suitable triangles planes created via original image pixels as vertexes. This method was implemented as C++ function. Root-mean-square-error (RMSE) between original and magnified image was calculated for quality testing. To compare images original image size was reduced the same times as later magnified. Quality of presented method is nearly the same as of well known linear interpolation. Processing speed is from 7 to 8 times faster than in case of linear interpolation. When magnification coefficient is integer, this method can be implemented with integer mathematic on processors without floating point instructions.
