Names	Description	Mathematical expression	Reference
Maximum entropy	Entropy maximum between presports attraction and background point		Kapur et al. [16]
Mean grayscale	All of the pixel point values are added up in the image and then divided by the number of all of pixels, and the average value is considered as threshold		Timo P Kaivosoja et al. [17]
Maximum intraclass variation	Maximum variation for the average grayscale value between the foreground region and whole image		Mhenni et al. [18]
