[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.

[A new system of chromosome analysis by image treatment: the chromoscan].

The authors present a new interactive system for chromosome analysis. All the operations are checked by the biologist with the use of a "mouse". This system avoids the photographic work and the manual classification.
