Embodiment Construction
[0026] According to the visual attention mechanism, the present invention first uses whether the image is clear as the salient condition to divide the salient image to be processed to obtain salient parts and non-salient parts. In this embodiment, a frequency-domain-based saliency extraction algorithm is used to obtain the required saliency map. The reason why the present invention proposes an image deblurring method based on visual salience is that different blocks in the image will have differences in the degree of blur or differences in blur directions. Secondly, even if a block in different blurs is estimated to have a Blur kernel, using this blur kernel to deconvolute the entire image will only make the effect of the unblurred part worse.
[0027] After the salient division, the non-salient part of the image can be obtained without the salient part, and then the fast deblurring algorithm can be used for this part to estimate the blur kernel, and for the salient part, it i...
