The traditional GrabCut algorithm and the improved GrabCut algorithm are used to simulate the multi-target wood surface defect images in single target,multi-target and complex background. The improved GrabCut algorithm was optimized for the defect image segmentation of the wood surface,which could effectively improve the defects of the traditional GrabCut algorithm,such as under-segmentation,over-segmentation,and susceptible to interference from regional bumps. The segmentation of all kinds of wood surface ...
