| Abstract: | According to the theory of interpolation based bintree (IBB), a compression algorithm for binary images is presented. The algorithm is then modified and a new one is proposed with due consideration of specific features of the electrical engineering drawing. Compared with the conventional compression method with step length, the compression ratio of the new algorithm is increased distinctly. An example is given. |
