Automatic Production of Hand-Painted Images

Abstract

Recently, the main focus of computer graphics has been the creation of photo-realistic images. In this paper, We consider hand-painted images with special emphasis on the generation of hand-painted images from natural pictures taken by a camera. We discuss the positioning of our painting algorithm in computer graphics, then explain the local image analysis. We provide further explanation of two painting algorithms based on data obtained from the image analysis. The Fourier transform and an oriented band-pass filter are used to obtain the local image analysis. One painting algorithm is generally a blurring algorithm in which the local image undergoes a blurring transform that depends on the local region. In the other painting algorithm, the image is formed from the painting of curved lines caused by the blush strokes. In this paper, we show hand-painted images using these algorithms.
