How to obtain key points in a grayscale image using shi-tomasi algorithm.

I have converted the video into individual frames. Now I want to extract all the key points in it. Can anyone help me in writing matlab code to do it?

Never heard of it. If it's not in the File Exchange, and no one answers here, you'll have to write it yourself, ask the paper authors for code, or hire someone to write it for you.

The other algorithm given in paper is Lucus Kannade algorithm.Can we do the same using Lucus Kanade algorithm,If so,can anyone help me doing it?

I don't know if it's the same, but someone could probably help you. So two questions they will want to know are:

1. What are your requirements (timing, costs, deliverables, etc.), and
2. What do you have to offer (funding, sample images, starting code, manpower, etc.)?
