Method of and apparatus for processing images

摘要

Ruled lines are extracted and fitted into a real 2-D space. Correspondence between fitted cells and template cells of a ruled line template is determined. For each pair of cells corresponding to each other, the position of each pixel in the template cell is mapped into a real position in the real 2-D space based on an affine transformation between the cells. A pixel value based on pixel values of a plurality of pixels in the image with positions adjacent to the real position is generated as a pixel value of the pixel in the template cell corresponding to the real position. A synthesized image corresponding to the image is generated by merging the ruled lines of the ruled line template with the pixels in the template cells having the pixel values as generated. A form template is obtained based on the synthesized images corresponding to the plurality of images.
