Problems solved by technology

Threshold segmentation can be considered to include the two dimensions of objective function calculation and optimal value solution method. The key to threshold segmentation can be considered as the determination of the objective function and the calculation method and optimal solution solution method. When the number of thresholds increases and When the dimensionality of the threshold representation increases, that is, when the dimensionality of the decision space for objective function optimization increases, the computational complexity will increase dramatically, as with many optimization problems. Existing solutions based on exhaustive methods and classical mathematical model methods require The calculation time often cannot meet the real-time and practical requirements of image threshold segmentation
[0004] As the depth of the network increases, the propagation of gradients in the training of existing medical image recognition models becomes more difficult
Since the gradient propagation is calculated by multiplication, when the model becomes too deep, the number of multiplications becomes more and more, and the problem of gradient disappearance and gradient explosion will appear. If the product is too small, the gradient will disappear, and the product When it is too large, it will cause the gradient to explode
And as the depth of the model increases, the accuracy of the model becomes saturated, no longer increases, and then declines rapidly, resulting in model performance degradation
