You could use a scanner and image processing software such as MATLAB. Does that answer your question fully? If not then read this

It is not possible for any computer program to automatically determine the area of interest for arbitrary objects -- not without guidance ahead of time as to what objects are of "interest"
To illustrate this I like to refer to the Cosmic Microwave Background Radiation, which was long thought to be just noise to be filtered out to get to the "interesting" images of the stars. Then it was determined to be real signal and a lot of effort (and literally billions of dollars) are being spent to map it in detail, a process which can require filtering out the stars. This illustrates that for any one image, the obvious foreground might be of interest to one person but the background might be of interest to other people. Therefore there cannot possibly be any program that separates out the area of interest of an image without being told what it is looking for.

It's up to you. Perhaps you want something that is brighter than everything else. Perhaps you want something that is a different color or shape or texture. There is no one answer - if you're doing the image analysis, then you should know!

Can you help to write a code for ROI extraction block for creating a simulinks for the project human recognition using combined features of finger texture and vein images...image size is 120*180.
