Abstract:A non-photorealistic rendering technique is a method to show various effects different from those of realistic image generation. Of the various techniques, flow-based image abstraction displays the shape and color features well and performs a stylistic visual abstraction. But real-time rendering is impossible when CPU is used because it applies various filtering and iteration methods. In this paper, we present real-time processing methods of video abstraction using open open computing language (OpenCL), technique of general-purpose computing on graphics processing units (GPGPU). Through the acceleration of general-purpose computing (GPU), 16 frame-per-second (FPS) or greater is shown to process video abstraction.

 

Key words:non-photorealistic rendering; video abstraction; general-purpose computing on graphics processing units (GPGPU); open computing language  (OpenCL)
