[Chromosome analysis using image processing. Recent aspects and perspectives].
After a brief description of the automatic metaphase finding and karyotyping systems actually available, the authors describe an interactive method for chromosome analysis. The edges of each chromosome are delineated automatically. The use of 256 grey levels and 512 x 512 pixels allows the accurate classification. The result may be recorded on hard copy, videotape or disk. Present improvements of the Chromoscan include histograms, quantitative studies and the use of an expert system.
