1) Describe the characteristics and creation of the analog image (Density, Contrast, Spatial resolution, Processing). 2) Describe digital image processing (Automatic rescaling - Brightness, Contrast, Look Up Table (LUT), Spatial Resolution, Edge Enhancement, Equalization).

The change from film-screen imaging to digital imaging has not only changed the image receptor but the processing of the image. This lecture looks at what the computer does with the image data extracted from image receptor.
