Abstract
A system has been developed that automatically analyzes and displays the distribution of brightness (intensity) of individual picture elements in any scene or portion of a scene that can be observed with a television camera. Consisting of video camera (any line rate), mini-computer, system interface, video monitor, and operator keyboard, the system permits an operator to select one or more areas of the video image and schedule the analysis and display of brightness distributions for each area. Readily mated to most common digital input-output (I/O) devices, the system software includes a convenient Executive Language which facilitates control by a relatively untrained operator. Typical applications include quantitative measurement of ratios of light or dark picture elements in either a "live" (patient examination), or archival (X-ray, photograph, etc.) scene. Further potential applications may lie in the area of automatic exposure control during X-ray examination or treat-ment. Such digital analysis systems could also be coupled to ther-mal imaging cameras. The system can also be adapted to automatically digitize existing ECG or similar records.
