... The MIDAS system is built along lines which should allow easy integration of complex analysis algorithms as well as allowing greater flexibility in interactive use and in the creation of user specific procedures from the basic building blocks. ... The present version which became available in 1984 follows a similar philosophy in its application program interfaces, but has been expanded to the new Standard Interfaces which have a broader base than previously. ...

A pattern analysis is made which yields four distinctive parameters: the number of pixels in the structure, the running pattern number within a frame, the pattern orientation (zero for singles and unresolved patterns; otherwise a three digit code, with the last digit specifying the orientation of the pattern and the first two the position of the pixel on the pattern ) and the distance (in pixels ) to neighbouring ...
