In printing industry,if the printing dot parameters are measured by way of image processing,binarization is a key step of image pre-proceesing,which affects the measuring accuracy.After analyzing all binarization methods,and considering the features of the printing dot image,a new method based on histogram concavity analysis is proposed.It takes the gray value of the valley between the peaks of histogram as the threshold for the binarization.Experiments show that compared with other methods… Expand
