This question is fairly hard to decipher. What exactly are you trying to find? The average difference between pixels in two images? Again, OpenCV can be told to do anything you could need it to do as long as you are comfortable programming in C/C++. If you give more detail, I could give you some sample lines of code to compare images.

The function cvAbsDiff will compute the difference between two images and could be used as a similarity metric.

Sir Actually I have to do palmprint pattern  matching.. do we have any function for this in OpenCV in which I pass two sets of image and it will do pattern matching for them and return true or false..
or I will input an image which will be  a line and it will return its properties i.e. its width,height,thickness,position etc.

If you are trying to match palmprints, you need to look at a lot more than just the main lines on the palm. This is a good read http://www.biometrics.gov/Documents/palmprintrec.pdf
Palmprint identification is not as accurate as fingerprint or iris scanning at the moment. It is still an active research area which is why you find more academic articles than you do programs.

In other words; a really good algorithm/function/program for palm matching does not exist yet. There are some decent ones out there, but researchers are not yet satisfied with the accuracy.

Dear Sir

Do you know about any good algorithm by which I can get b/w palm print image in which palm lines will be highlighted.

Actually I ahve tried few algo but all are image specific.

Thanks

Are you talking about all the little lines or just the major ones? Any program that you would find for the major lines would be very susceptible to the quality of the image, shadows, lighting, etc.
This paper seems to do almost exacly what you are talking about. It looks at the principle lines of the palm for matching http://www.me.ncu.edu.tw/ckjlin/public_html/course/mea003/1030%E7%9B%A7%E9%8C%AB%E6%96%B0_2.pdf

It has 71 citations so you could also browse the papers that referenced the above paper and see if they have any good ideas. http://scholar.google.com/scholar?hl=en&lr=&cites=13710784454641651880&um=1&ie=UTF-8&ei=OFJBTsG1AeaesQKh84TeCQ&sa=X&oi=science_links&ct=sl-citedby&resnum=7&ved=0CE0QzgIwBg
 Often with academic papers, you can contact the authors for code or data. That is usually the best way to make progress in this type of project.

Dear Sir

Suppose we want to contact any patent's author,
i.e. http://www.patentgenius.com/patent/7496214.html
how can we contact them?

Thanks in advance..

If you look below the names in 'other references,' you will see a list of papers, books, and such that the authors have written. Academic articles usually contain contact info.

For example, the second reference is an article by Zhang which contains his contact info. The article is here (via Google): http://ai.pku.edu.cn/aiwebsite/research.files/collected%20papers%20-%20palmprint/automated%20personal%20identification%20by%20palmprint.pdf

For books, you could check the bios and visit the website of the university at which the author currently works or just Google the name of the author.
