AI Technical Summary
首先，传统卷积神经网络因其固有的局部感受野限制，难以建模大范围、空间变化的模糊，复原效果有限且易产生伪影
[0015]As can be seen, this invention inputs an industrial image into a defocus blur suppression model. The encoder of the defocus blur suppression model includes multiple sparse iterative deformable scanning modules connected in sequence. The sparse iterative deformable scanning module includes a sparse routing branch, an efficient bypass branch, and an iterative deformable scanning branch. Pixel annotations are added to the input feature map through the sparse routing branch. The pixel annotations include clear pixels and blurred pixels. The clear pixels in the input feature map are processed by the efficient bypass branch to obtain a first feature through a first sequence scan calculation and reset. The blurred pixels are corrected in coordinate and order through the first scan calculation of the iterative deformable scanning branch. After correction, the new pixel values corresponding to the blurred pixels are arranged in order into a one-dimensional sequence. The one-dimensional sequence is processed by a second sequence scan calculation and reset to obtain a second initial feature. The second initial feature is fused with the blurred pixels in the input feature map to obtain a fused feature map. The second feature of the fused feature map is extracted through the second scan calculation of the iterative deformable scanning branch. The steps of the first scan calculation and the second scan calculation are the same. The first feature and the second feature are recombined to obtain the recombined feature output by the sparse iterative deformable scanning module. The recombined feature output by the encoder is input into the decoder of the defocus blur suppression model to obtain a defocus blur suppressed image.
