In this paper, we describe a hybrid algorithm to create a sketch-like portrait from an input image. First, a user manually selects the face region from the input image. We use an image based method to render the subjects facial features and enhance the shading areas. A stroke based method is then applied to non-face regions to render the silhouette, creases and some dark regions. We show some examples of sketching portraits created by our method and make comparisons to original input images.
