Abstract

One essential process in image rerendering is to replace existing texture in the region of interest by other user-preferred textures, while preserving the shading and similar texture distortion. In this paper, we propose the graphics processing units (GPU)-accelerated high dynamic range (HDR) image rerendering using revisited NLM processing in parallel on GPU-CUDA platform, to reproduce the realistic rendering of HDR images with retexturing and transparent/translucent effects. Our image-based approach using GPU-based pipeline in gradient domain provides efficient processing with easy-control image retexturing and special shading effects. The experimental results showed the efficiency and high-quality performance of our approach.
