Hello everyone,
I an new to the GWT. I have a doubt.
I would like to develop applications based on image processing.
An image processing library suitable for java is JavaCV.
Can I use that library while coding GWT applications?
Will that make any problem at client side when the application is
deployed to the app engine?

You won't be able to use JavaCV lib on the client side due to the dependencies it uses. There not available to the browser on all computers. You may be able to use the HTML5 canvas to do some of the image processing. The question is, could you do it in javascript?
