Gabor wavelet-fused multi-scale local level set ultrasonic image segmentation method

An image processing apparatus, comprising:

• a storage medium configured to store an image to be processed;
• and
• a processor configured to:
• obtain the image to be processed from the storage medium;
• perform filtering decomposition on the original image by using multi-directional Gabor wavelets, to obtain a plurality of intermediate images;
• fuse the plurality of intermediate images by taking maximum values, to obtain an enhanced image;
• construct a corresponding level set energy equation for the intermediate images;
• optimize parameters of the energy equation to enable an energy function to take a minimum value, to obtain an accurate position of an edge;
• and
• repeat optimizing the parameters of the energy equation until the energy function takes the minimum value to obtain a final edge.
