[0004] The existing binarization processing is for two-dimensional CT images, which cannot be applied to three-dimensional CT images, and the binarization of three-dimensional CT images
In addition, in the existing two-dimensional CT image binarization process, all two-dimensional CT images are binarized with fixed gray values, because the gray value range of each two-dimensional CT image is different. , using a fixed gray value to calculate the segmentation threshold of the foreground and background will greatly increase the amount of calculation, and there is an error in the accuracy of the segmentation threshold

The invention discloses a binarization processing method and system of a three-dimensional image. The method includes: step S100, obtaining grayscale values of pixel points in a to-be-processed three-dimensional image, and assembling a current grayscale value range through the grayscale values of the pixel points; step S200, obtaining a segmentation threshold through calculation according to the current grayscale value range and a preset binarization algorithm; and step S300, performing binarization processing on the to-be-processed three-dimensional image according to the segmentation threshold to obtain a binarization image corresponding to the to-be-processed three-dimensional image. The binarization algorithm in the binarization processing of the three-dimensional image can be appliedto three-dimensional pixel point coordinates for calculation of the segmentation threshold, the segmentation threshold is obtained through customized calculation according to each to-be-processed three-dimensional image, the calculating amount is small, the precision is high, a first grayscale value and a second grayscale value are set according to the current pixel point range of the to-be-processed three-dimensional images, and the binarization image is more natural and clearer.
Description
technical field [0001] The invention relates to the field of image binarization, in particular to a binarization processing method and system for a three-dimensional image. Background technique [0002] With the development of technology, CT images in medical images are developing from two-dimensional (2D) images to three-dimensional (3D) images in order to provide medical staff with more intuitive and clearer image information. [0003] In order to clearly highlight the outline of the target object, the CT image is generally processed by binarization. During the processing, the background is removed and only the foreground is reserved for calculation. [0004] Existing binarization processing is aimed at two-dimensional CT images, and cannot be applied to three-dimensional CT images to perform binarization on three-dimensional CT images. In addition, in the existing two-dimensional CT image binarization process, all two-dimensional CT images are binarized with a fixed gray...
