ROI of palmprint

I'm doing project on personal verification using palmprint biometrics. I want to extr开发者_Go百科act a Region of Interest (ROI) of palmprints in MATLAB.

In the image processing toolbox in matlab there are many ways to manually extract a region of interest. Personally, I often use "roipoly". (http://www.mathworks.com/help/toolbox/images/ref/roipoly.html)

Just type

m = roipoly(I);

where I is your image.

Auto ROI Extraction Locating the ROI of Palmprint images is a popular problem in biometrics and image processing. This is the primary step in developing a biometric system based on palmprint image recognition. There are a lot of methods presented already. This is one method I used.
