Specifically, when calculating the defect index, consideration is given to gray scale values, variance of noise estimation, peak signal-to-noise ratio and the like, which is beneficial to selecting a frame image with higher quality, wherein the variance of noise estimation is smaller, and the peak signal-to-noise ratio is larger.

and by analogy, continuously updating the value of sig by using the updating step bl until the absolute value between the two-dimensional entropy of the wavelet image of the low-frequency part after processing and the segmentation threshold obtained by calculating the wavelet image by using the maximum entropy threshold segmentation algorithm is smaller than a set absolute value threshold abth when the wavelet image of the low-frequency part is subjected to smoothing processing by using the value of sig, and taking the value of sig at the moment as the final value of sig.
By comparing the two-dimensional entropy of the smoothed image with the segmentation threshold of the maximum entropy threshold segmentation algorithm, the smoothing parameters are continuously adjusted, so that correct adjustment parameters can be selected, and the adaptivity of the smoothing function is enhanced.
