摘要：

Aiming at the low accuracy of visual measurement caused by the nonuniform illumination image of components during industrial processing and assembly, a multi-scale superpixel based homomorphic filtering method for the component image enhancement is proposed. Firstly, the image is segmented into multiple subblocks using superpixel segmentation in different scales. Secondly, different subblocks are homomorphically filtered at each scale. Finally, images of different scales which have been filtered are weighted according to the standard deviation and fused to get the enhanced image. The experimental results show that the proposed method can effectively improve the average value and average gradient value of the enhanced image.
