【Abstract】 Objective: To develop and apply automatic recognition system of leukocyte images.Methods: Data mining,pattern recognition,artificial intelligence and other techniques were applied to design this new system.Its accuracy,repeatability error,omission error,reliability,detection rate and correlation coefficients were evaluated according to manual differential counts(reference method).Results: The accuracy is 94.9%;repeatability error is 0.1%;omission error is 0.6%;reliability is 97.6%and detection rate is below 5 minutes per slide respectively.The correlation coefficients are the highest for neutrophils(0.997 1),lymphocytes(0.994 2) and eosinophils(0.989 9).For monocytes,the correlation coefficient is 0.982 2.The lowest correlations are basophils(0.852 8) and other cells(0.979 8).Conclusion: The evaluation shows this system has performance at least equal to that of direct clinical microscopy and could meet the clinical demand.更多还原
