Image Segmentation of Fiducial Marks with Complex Backgrounds Based on the mARU-Net
Circuits on different layers in a printed circuit board (PCB) must be aligned according to high-precision fiducial mark images during exposure processing. However, processing quality depends on the detection accuracy of fiducial marks. Precise segmentation of fiducial marks from images can significa...
