Reason image executes the processing first corroded and expanded afterwards again, handles image again to obtain；
The acnode detection device is connect with the Morphological scale-space equipment, for receiving the expansion process image, detects institute
The acnode quantity in expansion process image is stated, and when the acnode quantity is more than limitation, issues processing order again.
8. angiocarpy pattern certifying organization as claimed in claim 7, it is characterised in that:
First analytical equipment is connect with the Morphological scale-space equipment, for handling each of image again to described
Pixel carries out the luminance gradient value analysis of all directions, to be more than gradient value threshold value there are the luminance gradient value of a direction
When, determine the pixel for variation pixel；All directions are carried out to each of the image pixel that handles again
Luminance gradient value analysis include: each brightness value for obtaining the pixel of all directions of the neighborhood of pixel points, based on often
Each brightness value of each pixel in one direction determines the luminance gradient value of corresponding direction；
Second analytical equipment is connect with the pattern recognition equipment and first analytical equipment respectively, is used for unit figure
The image-region that variation pixel quantity transfinites during image planes are long-pending described will be handled again each in image as pending area
A pending area is sent to the pattern recognition as each high value region with the whole replacement pixel value filtering image
Equipment；Real-time resolution of the numerical value of the second analytical equipment selection unit image area based on the image of processing again,
The real-time resolution for handling image again is higher, and the numerical value of the second analytical equipment selection unit image area is bigger.
9. angiocarpy pattern certifying organization as claimed in claim 8, it is characterised in that:
The acnode detection device is also used to when the acnode quantity is less than limitation, issues single treatment order；
Wherein, the Morphological scale-space equipment is also used to after receiving the single treatment order, by the expansion process figure
Image is handled again as being used as；
Wherein, first analytical equipment and second analytical equipment are concentrated on same integrated circuit board.
10. angiocarpy pattern certifying organization as claimed in claim 9, which is characterized in that the mechanism further include:
FLASH stores equipment, connect with first analytical equipment, for storing and to described in first analytical equipment transmission
Gradient value threshold value.
