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
