Abstract

A Model 8100 Biomation Transient Recorder (BTR) and unique communication interface have been implemented into a video-computer system for the purpose of obtaining high-speed, high-fidelity quantitation of video signals. The BTR is complemented by a stop-action video disk recorder, three videographic display devices, an alphanumeric keyboard, and a light pen, all on-line to the computer and combined through the interface. Several computer programs have been written which provide selective digitization of any operator-specified area of a video frame, a variety of image processing capabilities (including subtraction, differentiation, logarithmic conversion, filtering, Fourier transformation, and deconvolution), and generation of information-dense yet comprehensible displays of the processed images (three-dimensional graphic and gray level displays). An entire video frame of 500 lines with 2000 samples on each line at 256 gray levels (1,000,000 8-bit picture elements) can be digitized by the BTR-video-computer system in 10 seconds. Smaller specified regions can be digitized in less time, with less spatial and/or amplitude resolution, if desired. Single televison lines can be digitized in real time.
