Abstract
The present invention comprises the first step of dividing a first image and a second image for each triangular patch having three adjacent feature points as vertexes, and calculating a planer projective transform matrix for the triangular patch, and the second step of finding a coordinate value, on the first image, corresponding to each of pixels in each of the triangular patches, on the second image using the planer projective transform matrix calculated for the triangular patch, and finding a coordinate value, on the first image, corresponding to each of the pixels which does not belong to any of the triangular patches on the second image using a planer projective transform matrix calculated for the triangular patch closest to the pixel.
