how to calculate circle number and distinguish the two kinds of circle

[muks]

No luck. The image is very uneven ..

Because I don't familiar with Labview. I used the Sobel in the Matlab.  Now, I want to use Labview.

Yes,  the result is not good. Through holes can be find easily, but the blind hole is difficult.

The back ground is also highly irregular and uneven. Try adjusting the lighting

I am sorry that the original picture is not  shoot by us, we don't have the camera, light and other equipment. The picture is from other company. It is difficult to change the lighting to get other picture.
