Embodiment Construction
[0037] The medical image lesion region segmentation method based on the energy functional model of machine learning of the present invention is as follows: image 3 As shown in the middle left half, follow the steps below:
[0038] Step 1: Initialize the parameter value of the feature array of the Gabor transform, and set the feature array to zero; at the same time, take the upper 1 / 2 part of the input medical image as the test set, and the lower 1 / 2 part as the training set, respectively for the training set The training image and the test image in the test set are subjected to Gabor transformation, and the general expression of the Gabor transformation is as follows:
[0039] plural form:
[0040]
[0041] Real part:
[0042]
[0043] Imaginary part:
[0044]
[0045] In formulas (1), (2), and (3), λ represents the wavelength of the sine wave, θ represents the direction of the filter, ψ represents the initial phase, σ represents the standard deviation of the Gaus...
