Method for extracting curling wheel on basis of two-stage ant colony algorithm
An ant colony algorithm and crimping wheel technology, which is applied in the field of extracting crimping wheels based on the two-stage ant colony algorithm, can solve the problem that the edge of the crimping wheel cannot be extracted well, the iteration effect depends on the selection of the initial snake point position, the curling wheel Problems such as wheel edge error

[0044] As shown in the figure, the method of extracting the crimping wheel based on the two-stage ant colony algorithm is implemented in the following steps:
[0045] A. The first stage:
[0046] (1) Extract the iris from the iris image and normalize it into a rectangle, then find the gradient image of the rectangle image and binarize it; set the parameters of the ant colony algorithm;
[0047] (2) Place artificial ants within the range of the binarized gradient rectangle image to complete initial positioning;
[0048] (3) Each artificial ant performs steps (4) to (5) in turn;
[0049] (4) Ant selects the next position;
[0050] (5) The pheromone update is carried out to the passing position of the artificial ants;
[0051] (6) If the specified number of iterations is not met, then skip to step (3), otherwise perform step (7);
[0052] (7) Find the row coordinates of the pixel point with the largest accumulated pheromone in each column of the image after iteration, and cal...
