Re: Image processing
anne,
Actually what you want to know about? I notice you have posted several posts on this question, but you didn't make your question clearer. Please state clearly what do you want to know.
Image processing is knowledge how to process the digital image. We input the digital photo inside the computer, using software such as MATLAB, do processing such as enhancement, binarisation, edge detection, compression, etc, then output as digital photo as well. In matlab, image is processed on the pixel level.
If you want to understand better about image processing, please download some ebooks here and read on it.

anne,
If you want to know in details, you should study some books. Try the processing in Matlab. For beginner, follow the guide of MATLAB help Image Processing toolbox, you will understand better what image processing can do.
Image processing is knowledge to process digital images, like filtering, noise removal, segmentation, edge detection, etc...Explore in MATLAB, it's very interesting. In matlab, a digital image is a matrix where all the component in the matrix is the pixel value of the image. You can manipulate the pixel of the image.
