A microcomputer-based vision system for area measurement.
A vision system for measuring the area of an arbitrarily shaped object is described. The algorithm consists of a gray-level thresholding technique combined with a region correction procedure based on mathematical morphology. All processing steps are carried out on a microcomputer system equipped with a video digitizer. The algorithm has been successfully applied to a number of images of medical interest including skin wounds and various microscopic-scale objects such as cell cross-sections and multicellular tissues. Excellent agreement between results obtained by the automatic method and by using standard mechanical means has been established experimentally. The approach is demonstrated by a number of experimental examples.
