8、 are spatial(plane)coordinates,and the amplitude of fat any pair of coordinates(x,y)is called the intensity or gray level of the image at that point.When x,y,and the amplitude values of f are all finite,discrete quantities,we call the image a digital image.The field of digital image processing refers to processing digital images by means of a digital computer.Note that a digital image is composed of a finite number of elements,each of which has a particular location and value.Theseelements are r

9、eferred to as picture elements,image elements,pels,and pixels.Pixel is the term most widely used to denote the elements of a digital image.Vision is the most advanced of our senses,so it is not surprising that images play the single most important role in human perception.However,Digital Image Processingunlike humans,who are limited to the visual band of the electromagnetic(EM)spectrum,imaging machines cover almost the entire EM spectrum,ranging from gamma to radio waves.They can operate on imag

10、es generated by sources that humans are not accustomedto associating with images.These include ultrasound,electron microscopy,and computergenerated images.Thus,digital image processing encompasses a wide and varied field of applications.There is no general agreement among authors regarding where image processing stops and other related areas,such as image analysis and computer vision,start.Sometimes a distinction is made by defining image processing as a discipline in which both the input and ou
