OBJECT-IMAGE - AN INTERACTIVE IMAGE-ANALYSIS PROGRAM USING STRUCTUREDPOINT COLLECTION

An interactive image analysis program has been developed which allows user observations to be recorded in a structured way. Its major object ive is to combine the user's capability of shape recognition with comp uter support for composite data structures and flow control. 'Object-I mage' is based on the image analysis program 'NIH Image' and can be us ed to describe cell details as a complex set of points. Vector graphic s has been added to provide visual feedback in the form of floating sy mbols, so the image is left unchanged. We presennt examples of yeast c ells and bacteria, where several parameters per specimen had to be mea sured, and we include statistics about precision and efficiency of int eractive data acquisition.
