IMAGE DEBLURRING METHOD BASED ON BRIGHT FRINGE INFORMATION IN IMAGE

摘要

Disclosed is an image deblurring method based on bright fringe information in an image. By means of bright fringes existing in a motion blur image, shape information about a blurring kernel is obtained. By means of combining the image with the blurring kernel, image restoration is constrained, and an accurate blurring kernel and a high-quality restored image are obtained. The method specifically comprises: selecting an optimal image block including optimal bright fringes; extracting obtained shape information about a blurring kernel; estimating the blurring kernel to obtain a final blurring kernel; and performing non-blind deconvolution, and performing restoration to obtain a clear restored image as a final deblurred image. According to the present invention, a test set of actually shot blurring images including bright fringes is established. By means of the technical solution of the present invention, an accurate blurring kernel and a high-quality restored image can be obtained, and the application value is high in the field of image processing.
