Detection and Removal of Long Scratch Lines in Aged Films

[[abstract]]Historical films usually have defects. We study the type of defects, and propose a series of solutions to detect defects before they are repaired by our inpainting algorithms. This paper focuses on a difficult issue to locate long vertical line defects in aged films. A progressive detection algorithm is proposed. We are able to detect more than 86% (recall rate) of effective line defects. These line defects are then removed step by step. The experiments use real historical video collected from national museum and public channel, instead of using computer generated noise. The results are visually pleasant based on our subjective evaluation by volunteers[[conferencetype]]國際[[conferencedate]]20060709~20060712[[iscallforpapers]]Y[[conferencelocation]]Toronto, Ont., Canad

Multi-layer inpainting on Chinese artwork [restoration applications]

[[abstract]]Digital inpainting uses spatial or frequency information to restore partially damaged/removed photos and artworks. Most restoration algorithms take a picture as a single layer. We propose a new approach, which subdivides a Chinese painting into several layers. Each layer is inpainted separately. The layer fusion mechanism then finds the optimal inpaint among layers, which are restored layer-by-layer. We apply the algorithm on Chinese and western drawing. The result shows a high PSNR value as well as a high user satisfaction. A demonstration of our work is available at: http://www.mine.tku.edu.tw/demos/inpaint.[[conferencetype]]國際[[conferencedate]]20040627~20040630[[booktype]]紙本[[iscallforpapers]]Y[[conferencelocation]]Taipei, Taiwa
