2. Why image processing? Images play an important role in human perception: It is said that one picture is worth more than ten thousand words. Applications of image processing: improvement of pictorial information for human interpretation processing of image data for tasks such as storage, transmission extraction of pictorial information Imaging Vs. Image Processing

3. Digital Image An image is a two-dimensional function, f(x, y), where x and y are spatial coordinates When x, y, and f are all finite, discrete quantities, we call the image a digital image.  Pixel: A digital image is composed of a finite number of elements, each of which has a particular location and value. These elements are called picture elements, image elements, pels, and pixels.
