Interframe Image Processing
John Merchant · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1982
To the layman, an image is seen as a single entity. He might say, as he holds up a photograph, "this is a view of my house". His choice of words reveals his perception of it as a single entity. The professional image processor, on the otherhand, must deal with the same image as a vast array of individual pixels, each one having its own numerical (intensity) value.
