Oriental Brush Rendering for Input Lines Using HMM

Abstract

Our purpose is to transform an input line into an oriental brush stroke automatically. However, there are many parameters required for the rendering, and it is not simple to determine them from input lines. In order to solve this problem, we use a continuous HMM which is one of the machine learning methods. We prepare the captured stroke data as training data, and then train a continuous HMM. We can obtain an oriental brush-like painting which is based on physical characteristics of brush and a drawing style by applying the trained continuous HMM to an input line.
