| Summary: | 碩士 === 國立交通大學 === 多媒體工程研究所 === 97 === The paper presents a method for converting original images to pencil sketch -styled images. Main steps in the process consist of image grouping, block analysis and stroke generate.
In the first step, the original image will be divided into several blocks by image simplification technology. The next is to analyze various imagery characteristics within each block, for instance, intensity, block size and pixel angle, etc. Stroke Model will then generates the pencil-sketch strokes based on the characteristics of these blocks.
Through a series of experiments and observations, the Stroke Model is turned and the effects are observed. Finally, the system can produce a satisfactory pencil-sketch-styled images.
