7 Digital Image Processing 7 Examples of Fields that Use Digital Image Processing The principal energy source for images in use today is the electromagnetic energy spectrum. The electromagnetic spectrum arranged according to energy per photon.

8 Digital Image Processing 8 Examples of Fields that Use Digital Image Processing Gamma-Ray Imaging Nuclear medicine and astronomical observations. In nuclear medicine, the approach is to inject a patient with a radioactive isotope that emits gamma rays as it decays. Images are produced from the emissions collected by gamma ray detectors.

10 Digital Image Processing 10 Examples of Gamma-Ray Imaging Examples of gamma-ray imaging. (a) Bone scan. (b) PET image.

11 Digital Image Processing 11 Examples of Fields that Use Digital Image Processing X-ray Imaging The oldest sources of EM radiation used for imaging. The best known use of X-rays is medical diagnostics, but they also are used extensively in industry and other areas, like astronomy.

12 Digital Image Processing 12 Examples of X-ray imaging (a) Chest X- ray. (b) Aortic angiogram (c) Head CT. (d) Circuit boards. (e) Cygnus Loop. (a)‏ (b)‏ (c)‏ (d)‏ (e)‏

13 Digital Image Processing 13 Examples of Fields that Use Digital Image Processing Imaging in the ultraviolet band Lithography, industrial inspection, microscopy, lasers, biological imaging, and astronomical observations. Fluorescence microscopy - an excellent method for studying materials that can be made to fluoresce, either in their natural form (primary fluorescence) or when treated with chemicals capable of fluorescing (secondary fluorescence).

14 Digital Image Processing 14 Examples of ultraviolet imaging. Fluorescence microscope image of normal corn, and a corn infected by “smut,” (a) Normal corn. (b) Smut corn. (Brand - Getreidekrankheit) (a)‏ (b)‏

15 Digital Image Processing 15 Examples of Fields that Use Digital Image Processing Imaging in the visible and infrared bands Industrial image processing Light microscopy Remote sensing,......and much more

16 Digital Image Processing 16 Examples of Infrared Images Infrared satellite images (Europe + Africa)‏

17 Digital Image Processing 17 Examples of Fields that Use Digital Image Processing Imaging in the microwave band The dominant application of imaging in the microwave band is radar.
