Thermal image defect extraction based on two image segmentation algorithms

Pulse eddy current thermal imaging detection technology is a new type of non-destructive detection method.It studies the data characteristics of thermal imaging surface defects,combines the otsu segmentation algorithm with the maximum entropy segmentation algorithm,and proposes the otsu segmentation algorithm based on the maximum entropy.Segmenting the defects in the thermal image can effectively identify the edges of the target defect.Experimental results show that compared with other traditional segmentation algorithms,it has better defect extraction effect.
