XU Qing, FAN Jiu-lun. New three-dimensional Otsu segmentation algorithm based on decomposition histogram[J]. 2017, 36(1): 119-122+126. DOI: 10.13873/J.1000-9787(2017)01-0119-04.
Otsu image processing is a common method for image segmentation. In order to solve problem of high time complexity and low resistance to noise ratio of faults of traditional three-dimensional Otsu method
propose using histogram projection technology and histogram decomposition technique for three dimensional histogram dimensionality reduction
it is split into a one-dimensional histogram and a two-dimensional histogram
respectively use one-dimensional Otsu method and two-dimensional curve Otsu method to resolve threshold
and with the threshold value to determine image point classification. Experimental comparison results show that segmentation effect of the method is good
