Digital Image Processing 2nd Edition, Rafael C. Gonzalvez and Richard E. Woods. I don't know if it is available in soft copy form or not. You can check on Google. Thanks.
By the way, its not the correct time to study from standard books because they are very thorough and you will have to give many hours (which is obviously not possible at this point) to understand topics . What i can do for you is, you can mail me your topics and i will make you understand if you want to. Thanks
