Applying Method of Generating Checkered Pattern Images Using Prewitt Filter to RGB-D Images

Abstract

A non-photorealistic rendering (NPR) method for automatically generating checkered pattern images from gray-scale photographic images using Prewitt filter with an expanded window size has been proposed. In this paper, we propose an extension of the conventional method to apply to RGB-D images. Our method can change the size of the checkered patterns depending on the depth. To verify the effectiveness of our method, we conducted experiments that are visually confirmed the checkered patterns by changing the parameters in our method. As a result of the experiment, it was found that the size of the checkered patterns can be automatically changed according to the depth. Additionally, it was found that the size and density of the checkered patterns can be adjusted by changing the value of the parameters.
