Abstract
Aiming at the problem of Criminisi’s image inpainting algorithm that the inpainting order does not take full advantage of the structure properties,we propose an exemplar-based image inpainting algorithm which uses HSI colour space to modify.By mapping the image onto HSI colour space when calculating the priority weighting function,the algorithm introduces the concepts of hue gradient and saturability gradient,as well as introduces to information quantity parameter the statistics of mean and variance of gradient,thus fully extracts the structure properties of image and makes the inpainting order tend to be rationalised.Besides,by utilising the neighbourhood similarity of image,the algorithm reduces the calculation amount of the inpainting process.Results of contrast experiment show that this modified algorithm achieves better improvement in inpainting qualities on various kinds of images.关键词
