Help Needed..Fingerprint Identification..Image Manipulation

[Snakehead52]

Norfolk State University Student (Help Needed):

I'm working on Fingerprint Identification using image correlation and/or a feature-based approach.  First, Goal is to minimize the lines of the minutia so that they are one pixel thick.  What services does Labview offer that will help me accomplish this task??

If you have IMAQ, you can use the function "IMAQ Skeleton.vi"

I use the skeleton VI and it didn't make the line one pixel thick.  The image is still too noisy.  any other suggestions?

Can you attach a couple of sample images? Maybe there are steps that can be taken up front to make the image processing more efficient.

Hey Snakehead...,

Have you tried improving your original image with better lighting, better camera, better lens, etc.? What image processing have you done already, or are you starting from scratch? I agree with AnalogKid in providing some sample images to the forum so we can get an idea of what you are working with. Have you performed any morphology processing on the image? Have you tried edge detection functions? There are numerous functions that NI provides with their NI Vision software that will help you process your image, it is just finding the right combination that is the toughest part. Last, if you do have the Vision software, I might suggest taking a look at the Vision concepts manual to get an idea of the different functions and their capabilities. Let us know what kind of images you are working with and what you have done so far, and last, what you would like to eventually see. Thanks, and have a great day.
