Claim 3:
4. The method according to claim 3, wherein the two-dimensional coordinates include a first coordinate in a horizontal axis direction and a second coordinate in a vertical axis direction; and
determining the coordinates of the predicted center point of the lesion region, the predicted length of the lesion region, and the predicted width of the lesion region, according to the largest feature point, the maximum feature value, the two-dimensional coordinates, and the preset feature threshold includes:
determining the two-dimensional coordinates as the coordinates of the predicted center point;
calculating an absolute value of a feature difference between the maximum feature value and the preset feature threshold;
obtaining a first feature point and a second feature point in the horizontal axis direction of the two-dimensional feature maps, and a third feature point and a fourth feature point in the vertical axis direction of the two-dimensional feature maps, according to the absolute value of the feature difference and the two-dimensional coordinates of the largest feature point;
obtaining a first coordinate of the first feature point in the horizontal axis direction, and a second coordinate of the second feature point in the horizontal axis direction;
obtaining a third coordinate of the third feature point in the vertical axis direction, and a fourth coordinate of the fourth feature point in the vertical axis direction;
calculating the predicted width, according to the first coordinate and the second coordinate; and
calculating the predicted length, according to the third coordinate and the fourth coordinate.
