Abstract :
DAPR is a digital automatic pattern recognition system, designed to find and measure events in bubble chamber film without manual intervention. It is able to measure film which has come directly from the photographic development process, and to produce on magnetic tape a digital abstraction of the information contained in the film, from which a subsequent selection of desired events takes place by means of a digital scanning process.
