I need to convert a sample fingerprint image into black and white, where the finger color acts as a foreground color and the background color is black. It's needed in MATLAB code format.... For example, I need to convert image from:
(source: wikimedia.org)

to a black-and-white image.

EDIT: I used multiple masks, like prewitt: http://i43.tinypic.com/1z7w60.jpg Canny Detector: http://i44.tinypic.com/2ujtt6u.jpg

I'm not getting lines on blurry here.

  • Ugh, the images _could_ be minimized... – Eitan T Jun 27 '13 at 06:45
  • you cannot expect to recover the fingerprint at the blurry parts of the finger. Please post a new input image that is more representative of your task. – Shai Jun 27 '13 at 06:49

As Shai said, you can only expect good results in regions of the image that are in focus. Try starting with these algorithms:

  • Yeah, that's one issue with the project.... Getting all the lines to be focussed. Maybe a capacitive sensor or simple plastic. Canny Edge detector looks feasible. I'll try it ASAP. – Aqui1aZ3r0 Jun 27 '13 at 07:47
