I am doing a project on hand recognition and in a paper that i read they have converted rgb to gray and gray to binary...

Please post your image so we can see what you're talking about. Use the image icon above the edit box. It's best to have an image if you're going to give advice on image processing, wouldn't you agree?

Converting to binary is often used in order to find a Region Of Interest -- a portion of the image that is of interest for further processing. The intention is binary, "Yes, this pixel is of interest" or "No, this pixel is not of interest".

If you're trying to recognise the hands themselves, it may be very helpful to use the colour information - so it might be more successful to go from rgb to binary, selecting the pixels of interest according to where they lie in colour space.

hi,
This transformation is useful in detecting blobs and reduces the computational complexity, however many other studies perform on the degree of colors like in skin detection like @Young pointed in his comment.
