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.
