Automatic generation of pen-and-ink drawings from photos

In this paper, a new algorithm for automatic generating pen-and-ink drawings from photos is presented. The basic processing step of our system is the edge extraction based on the multiresolution property of wavelet transform. In order to enhance the variations in texture and tone, the proposed algorithm includes two binarization steps and a noise removing step. Experimental results show that the generated pen-and-ink drawings are of high quality, which accurately illustrate the scenic contents of the original photos.
