MRC Picture Language(ID:7292/mrc002)

Language for analysis and manipulation of images 


Rutovitz et al at the Medical Research Council's Radiation Research Unit, 1968

Draws on Pax, SLPL, BUGSYS to make image manipulation language, bulit as an extension to FORTRAN IV

G. review of Hilditch 1969 view details Abstract: If one looks at a typical photograph of the microscopic chromosomes that are attracting so much research, medical, and even criminological interest today, one might understand why even an expert technician can cope Neolith typing only 50 cells a day. As the author comments, these minute structures can look like "two equal sausages lying side by side and twisted together somewhere along their length." The author then modestly points out that these are not "very amenable to programming." The remainder of the paper goes on to describe the basic principles being used at the Cytogenics Research Unit in London to make these "twisted sausages" amenable to programming.

    A FIDAC scanner connected to an IBM 7094 is used to process the images, recognize edges and shapes, exclude "noise," and separate touching chromosomes. No details are given of the algorithms used to recognize, separate, and classify the chromosomes, but they obviously exist, and the workers at the Cytogenetics Research Unit are obviously very sophisticated and advanced in the technology of this particular branch of pattern recognition.

    The paper, although to this reviewer unnecessarily long, is well worth reading.
