A computer-oriented approach to the analysis of microscopic images has been developed around CYDAC, a data conversion system which scans through the microscope and records the optical information in digital form on magnetic tape. The quality of the optical information thus made available to the computer is surprisingly good, as evidenced by reconstructions of the original image using the high-speed printer. Preparations for the computer- interpretation of scanned images are underway, using blood cells as a model system. Parallel attempts to classify human chromosomes by means of CYDAC scans have given very encouraging preliminary results.

Die Verfasser berichten über einen Computer-gesteuerten Versuch der Analyse mikroskopischer Bilder mittels CYDAC, eines Datenumwandlungssystems, das das mikroskopische Gesichtsfeld abtastet und die optische Information in digitaler Form auf Magnetband überträgt. Die Qualität der dem Computer auf diese Weise verfügbar gemachten optischen Informationen ist überraschend gut, wie die Rekonstruktion der Originalbilder auf einem Schnelldrucker erweist.

Vorarbeiten zur Computer-Interpretation abgetasteter Bilder mit Blutzellen als Modellsystemen sind angelaufen. Gleichzeitige Versuche, menschliche Chromosomen mit Hilfe von CYDAC zu klassifizieren, haben zu vielversprechenden ersten Ergebnissen geführt.
