Microcomputer video image analysis

Abstract

SUMMARY A review of aspects relating to microcomputer video image analysis is presented. The technical limitations of early systems have been surpassed by high performance video digitizers and microcomputers which are now widely marketed. Commercial systems based on these devices are increasingly available. Also, with the programming skills in most laboratories today, software development for specific applications is a practical proposition provided that sufficient expertise in video and computer technology is available. Considerations necessary for effective hardware selection and software design are discussed by example of the application to light microscope densitometry. Attention is drawn to errors which can arise when employing conventional video systems for analytical purposes.
