摘要

In this paper, we introduce a new brush stroke generation method for painterly effect. Instead of using the gradient of the source image to determine the stroke direction, we extract regions that can be drawn in one stroke using Maximum Homogeneity Neighbor filtering followed by identification of connected components considering the homogeneity of pixels. We can make a brush stroke from each component based on a least squares approximation to the medial axis. This method results in realistic looking brush strokes of varying width that have irregular directions where necessary.
