Embodiment Construction

[0039] As shown in the figure, the method of extracting eyelashes based on the improved ant colony algorithm is implemented in the following steps:

[0040] (1) Initialize the pheromone in the eyelash extraction area; put an artificial ant, and set the parameters of the algorithm;

[0041] (2) Each artificial ant performs step (3) and step (4) sequentially;

[0042] (3) The artificial ant chooses the position of the next step, and the end condition is to finish the prescribed number of steps s or to have no way to go;

[0043] (4) The pheromone update is carried out to the passing position of the artificial ants;

[0044] (5) After all the artificial ants have traversed, the pheromone concentration at each position of the image is obtained, and then the edge of the eyelashes is extracted using the OTSU algorithm;

[0045] (6) integrating the obtained eyelash edges to obtain complete eyelashes;

[0046] (7) Sequential sliding windows are used to eliminate noise to obtain the...

Abstract

The invention belongs to the technical field of iris recognition, and in particular relates to a method for extracting eyelashes based on an improved ant colony algorithm, which is implemented according to the following steps: (1) initializing the pheromone in the eyelash extraction area; placing an artificial ant, and setting each parameter of the algorithm; (2) ) each artificial ant executes step (3) and step (4) in turn; (3) the artificial ant selects the position of the next step, and the end condition is to finish the prescribed number of steps s or to have no way to go; (4) the artificial ant Update the pheromone at the passed position; (5) After all the artificial ants have traversed, get the pheromone concentration at each position of the image, and then use the OTSU algorithm to extract the edge of the eyelashes; (6) Integrate the edge of the eyelashes to get a complete eyelashes; (7) Sequential sliding windows are used to eliminate noise to obtain the final eyelashes. In the present invention, when the distance between artificial ants is about 25 pixels, the algorithm can not only ensure the speed of eyelash detection, but also ensure the effect of eyelash detection.

Description

technical field [0001] The invention belongs to the technical field of iris recognition, and in particular relates to a method for extracting eyelashes based on an improved ant colony algorithm. Background technique [0002] Iris recognition is considered to be one of the most potential biometric identification methods due to its universality, uniqueness, stability, non-invasiveness and other advantages. The main function of eyelashes is to prevent foreign matter such as dust from entering the eyes. However, when extracting iris features, eyelashes may sometimes block the iris to varying degrees, thus affecting the extraction of real iris features. Therefore, in the preprocessing stage of iris recognition, accurately detecting eyelash occluded areas is a very important link to ensure the accuracy of iris recognition. [0003] At present, the main methods of eyelash detection include: Kong Waikin, etc., divide the eyelashes into two types: scattered and aggregated, and use a...
