Embodiment 1
[0031] refer to figure 1 , a three-dimensional image segmentation method based on a three-dimensional improved pulse-coupled neural network, the operation steps are:
[0032] (1) Read the image sequence.
[0033] (2) Use the 3D IPCNN segmentation algorithm to segment the read image sequence as a whole to obtain a binary image sequence.
[0034] (3) Using mathematical morphology method to smooth the edge of the region of interest.
[0035] (4) Reconstruct the region of interest with the method of volume rendering.
Embodiment 2
[0037] This embodiment is basically the same as Embodiment 1, and the special features are:
[0038] see figure 2 , the IPCNN segmentation algorithm model is extended from two-dimensional to three-dimensional, and the 3D IPCNN segmentation algorithm model consists of three parts: receptive field, modulation part and pulse generation. Its principle mathematical equation is described as:
[0039] f ijk [n]=I ijk (1)
[0040] L ijk [n]=∑W ijklmn Y lmn [n-1] (2)
[0041] u ijk [n]=F ijk (1+βL ijk [n]) (3)
[0042] Y ijk [ n ] = 1 U ijk [ n ] > θ ijk [ n - ...
