Embodiment Construction
[0021] to combine figure 1 Describe this embodiment, the steps of this embodiment are as follows:
[0022] Step 1: Based on the learning sample pictures of a data set, use the anisotropic diffusion method to construct a scale space. Manually and accurately segmented by ultrasound image experts, using Gabor filter to extract the texture features of the contour edge of the ultrasound image in different directions, different frequencies and different scales;
[0023] Step 2: Automatically initialize the starting contour model, starting from the roughest scale, guided by the texture features extracted by learning and the directional gradient features of the model contour edges, combined with the shape space constructed by kernel density estimation, together under the subspace constraints Find the target contour and perform preliminary segmentation. The specific implementation steps are:
[0024] Step A: For each control point on the model outline, inspect the adjacent coordinate...
