Digital processing did not originate with remote sensing and is not restricted to these data. Many image-processing techniques were developed in the medical field to process X-ray images and images from sophisticated body-scanning devices. For remote sensing, the initial impetus was the program of unmanned planetary satellites in the 1960s that telemetered, or transmitted, images to ground receiving stations. The low quality of the images required the development of processing techniques to make the images useful. Another impetus was the Landsat program, which began in 1972 and provided repeated worldwide coverage in digital format. A third impetus is the continued development of faster and more powerful computers, peripheral equipment, and software that are suitable for image processing.Expect EE368 to be offered each year. Note that we will not cover compression in EE368. Image and Video Compression will be discussed in EE 398A/B.
