Embodiment seven

Fig. 7 is a kind of processing of concentric circles ring-shaped figure finger URL recognition positioning method of another embodiment of the invention Flow diagram, the method operate on the computer system comprising this method, as shown in fig. 7, comprises following processing walk It is rapid:

S1. image is traversed line by line, finds the doubtful pixel group of all rows: in same a line, adjacent same colour Plain ratio of number meets the pixel group of the ratio between each annular width of concentric circles ring-shaped figure finger URL, it is believed that and it is capable doubtful pixel group, The position of the doubtful pixel group center pixel of row in the picture is found, by the position of the doubtful pixel group of row and its center pixel in the picture It sets and (is denoted as La) and be added in set A；

S2. image is traversed by column, finds all doubtful pixel groups of column: in same row, adjacent same colour Plain ratio of number meets the pixel group of the ratio between each annular width of concentric circles ring-shaped figure finger URL, it is believed that and it is the doubtful pixel group of column, It finds and arranges the position of doubtful pixel group center pixel in the picture, the position of doubtful pixel group and its center pixel in the picture will be arranged It sets and (is denoted as Lb) and be added in set B；

S3. it looks for the central point of concentric circles ring-shaped figure finger URL: in two set A, B, finding out and be located at two collection Element of the distance between the center pixel of two elements in conjunction less than given threshold A is to (being denoted as (La, Lb)), it is believed that this yuan The central point of the center pixel line of element pair is the central point of concentric circles ring-shaped figure finger URL.

Optionally, before carrying out step S1, image is pre-processed, it is preferred that it is described pretreatment include greyscale transformation ( Color image is transformed to gray level image), it is processed on gray level image, is conducive to speed up processing；Preferably, in greyscale transformation Afterwards, further, black and white conversion process is done, black and white transformation herein selects a numerical value as black in the middle part of pixel value range The cut off value of white pixel (cut off value is divided into one of black or white)；Preferably, the middle part is in pixel value interval Heart point respectively extends 30% no more than pixel value range, preferably 10% to two sides.

In concentric circles ring-shaped figure finger URL as shown in Figure 1, when comprising 2 layers of annulus, a center circle, from outer layer dark circles Ring rises, and by the center of circle of center circle, reaches the line segment of the other side of outer layer black annulus, the color passed through is successively: black, It is white, black, white, black, and the ratio of each section of colored pixels number is 1:2:2:2:1；

In concentric circles ring-shaped figure finger URL as shown in Fig. 2, when comprising 3 layers of annulus, a center circle, from outer layer dark circles Ring rises, and by the center of circle of center circle, reaches the line segment of the other side of outer layer black annulus, the color passed through is successively: black, It is white, black, white, black, white, black, and the ratio of each section of colored pixels number is 1:2:1:2:1:2:1.

It is illustrated below with concentric circles ring-shaped figure finger URL shown in FIG. 1, processing method shown in Fig. 2 and Fig. 1 class Seemingly.

In step sl, image is traversed line by line, finds the doubtful pixel group of all rows:

In same a line, from left right (or from right-to-left) traversal, after finding first black picture element, continuous black is calculated The quantity X1 of pixel；

Continue quantity X2, Y1=X2 the ÷ X1 for calculating continuous white pixel backward, if the absolute value that Y1 subtracts 2 is less than setting Threshold value three, it is believed that find the stem of the doubtful pixel group of row；

Quantity X3, Y2=X3 the ÷ X2 of continuous black picture element is calculated backward, if the absolute value that Y2 subtracts 1 is less than given threshold Three, it is believed that the stem for finding the doubtful pixel group of row plays first three section；

Quantity X4, Y3=X4 the ÷ X3 of continuous white pixel is calculated backward, if the absolute value that Y3 subtracts 1 is less than given threshold Three, it is believed that the stem for finding the doubtful pixel group of row plays first four sections；

Quantity X5, Y4=X5 the ÷ X4 of continuous black picture element is calculated backward, if the absolute value that Y4 subtracts 0.5 is less than setting threshold Value three, it is believed that find the doubtful pixel group of row.

The threshold value three, value is preset, less than 0.2, preferably 0.08；In corresponding two annulus or center circle Width (or diameter) ratio difference when, threshold value three can also be set as different values.

After finding the doubtful pixel group of row, the position of the doubtful pixel group head and the tail pixel of record row, center pixel position (with Row, column coordinate representation in image).

Step S2 looks for the processing for arranging doubtful pixel group, looks for the processing method of the doubtful pixel group of row consistent with S1, and difference is, It traverses by column, each column traverses from up to down (or bottom-up).

In step S3, all elements traversed in set A calculate the doubtful pixel group of the row to the either element in set A Center pixel, (position of center pixel is in image for the distance of the center pixels of all doubtful pixel groups of column in distance set B Interior row, column coordinate representation is calculated with Calculation Plane distance between two points formula)；

If the distance is less than given threshold A, it is believed that the position where the doubtful pixel group of the row, the doubtful pixel group of column is Concentric circles ring-shaped figure finger URL；The threshold value A is less than or equal to the 30% of the pixel quantity of the doubtful pixel group of row, preferably less than 10%；

The doubtful pixel group of the row, the central point that the midpoint for arranging doubtful pixel group line is concentric circles ring-shaped figure finger URL.

Optionally, as shown in figure 8, further including following processing step, it is preferred that including following processing step:

In step S4, the row that the threshold value B value is less than or equal in related two concentric circles ring-shaped figure finger URLs is doubted Like the 30% of the pixel quantity maximum value (or minimum value) of pixel group, preferably less than 10%.
