Lecture # 02: Basic Concepts of an Image. Monday 20-Nov-23 What is an Image?  An Image is a projection of 3D objects on 2D surface. OR  An Image is a 2D light intensity function of form f(x,y). Where x & y denotes the spatial co-ordinates and the value of f @ (x,y) is brightness of the image at that point. What is an Image? As Image is light Intensity function, so 0
