ABSTRACT
A new non-photorealistic rendering method using a depth map has been developed, on the basis of which a real-time cartoon-like video converter called Takumi was created. Many systems have been proposed that convert a given image into a non-photorealistic one. Images that these conventional methods render lack in perspective, due to processing being equally applied to the whole image. A method has been developed that solves this problem using a depth map. The proposed method generates cartoon-like jump edges on the basis of depth information and adjusts the tone color of the region of the same plane considering the values of normal lines. Takumi, implemented with the proposed method using Kinect, works at the frame rates or 30fps. Takumi is expected to be used in the fields of entertainment and content production.
