Abstract

In order to address the detection and segmentation of partial blur for natural images,a no-reference and training-free algorithm was proposed.Firstly,the test image was re-blurred by a Gaussian low-pass filter.Secondly,the pixel-wise singular value decomposition within N×N neighborhoods for both the test image and the re-blurred image were conducted to obtain the ratio of the end singular value to all singular value.According to the ratio,the blurriness distribution function was structured and the blurriness distribution map was drawed.Finally,combined with the K-means clustering algorithm and the erosion and dilation operations, the test image could be segmented into blur region and clear region.Experiment results show that the proposed approach can effectively detect and segment the partial blur image and behave well at precision, recall and F-score.
