An image-processing system, motion analysis oriented (IPS-100), applied to microscopy.

This paper describes a real-time video image processing system, suitable for image analysis of stationary and moving images. It consists of a high-quality microscope, a general-purpose personal computer, a commercially available image-processing hardware module plugged into the computer bus, a b/w TV-camera, video monitors and a software package. The structure and the capability of this system are explained. The software is menu-driven and performs real-time image enhancements, real-time mathematical and morphological filters, image segmentation and labelling, real-time identification of moving objects, and real-time analysis of their movements. The program is available in listing form.

Algorithms

A procedure for the extraction of object features in microscope images.

A program for a detailed and fast feature extraction procedure on objects from a digitized microscope image is presented. The single-pass algorithm labels the pixels of the image that are above a selected threshold, and connects those which belong to the same object. A data structure addressable as an associative memory is created, thus avoiding the use of any recursive procedures. A detailed description of the procedure, which extracts features such as integrated optical density, area and baricenter coordinates, is presented.
