Title:
IMAGE DEBLURRING METHOD BASED ON BRIGHT FRINGE INFORMATION IN IMAGE
Document Type and Number:
WIPO Patent Application WO/2017/190432
Kind Code:
A1
Abstract:
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.
