Progressive image transmission (PIT) transmits the most significant portion of a picture, followed by its less important portions. The mechanism call be used in Web-based applications while users are browsing images. However, most PIT methods use the same pixel interpolation scheme for the entire picture, without considering the differences among image(More)
Video inpainting uses spatial-temporal information to repair defects such as spikes and lines on aged films. We propose a series of new algorithms based on adjustable thresholds to repair different varieties of aged films. The main contribution is an automatic spike and dirt detection mechanism. We prove that if appropriate threshold is once decided by the(More)
The popularization of digital technology has made shooting digital photos and using related applications a part of daily life. However, the use of flash, to compensate for low atmospheric lighting, often leads to overexposure or glossy reflections. This study proposes an auto-detection and inpainting technique to correct overexposed faces in digital(More)
Digital image inpainting is a technique that can repair a portion of damaged or removed image by means of automatic mechanisms. Image inpainting tools can be applied to repairing damaged historical documents. In this paper, we propose an adaptive mechanism, which is based on a color interpolation mechanism. The repairing procedure checks the surrounding(More)
There exist many texts and symbols in a natural scene, such as billboards and traffic signs, serving the purpose of relaying information or offering guidance. With rapid advances in information technology, detection and extraction of texts in images and related research into this area have become increasingly important. Here, we present an intelligent(More)
Image inpainting (or image completion) techniques use textural or structural information to repair or fill damaged potions of a picture. However, most techniques request a human to identify the portion to be inpainted. We developed a new mechanism which can automatically detect defect portions in a photo, including damages by color ink spray and scratch(More)
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(More)
