Dr. Liang's lecture on Image Processing was the basic overview of how we can enhance an image  and obtain important information from the image. I am also enrolled to Digital Image Processing (DIP) course and we have to study different techniques to process an image. Filtering, noise reduction, edge detection, segementation are few of them. The interesting thing about image processing, as mentioned by Dr. Kahol) is that it is the applied domain of mathematics. We can apply different mathematical functions and see the results in the image. When we consider an image as a matrix of pixel values, then we can visualize different mathematical models like masking, filters, transforms in an image. In medical field, we can enhance CT, MRI, and/or XRay images using various techniques that would help a doctor to diagnose disease(s). In fact, the way CT, MRI, X-Ray are generated, they are also application of image processing.
