| Abstract: | This paper is concerned with the digital image enlarging and lessening. On the basis ofthe analysis on the existing enlarging and lessening algorithms used in binary matrix grayscale irnages and in engineering drawings,the image transformation idea based on region fea-tures is proposed.The images are enlarged or lessened by segments rather than by pixels. New algorithms are given and discussed. |
