Abstract: Nonlinear mapping technique is applied in automatic cell image analysis and decision making procedure proposed.The result with the two-dimensional display isused for diagnosis according to the entire cell distribution or interactive groupings.Cancer cells including serious hyperplasia can be distinguished from normal cells whichhave clear laminations.This technipue provides a useful visual tool for automatic cancer cell detection.All the algorithms are written in BCY language and the program has been runon TQ-16 computer.
