Automated identification of normoblast cell from human peripheral blood smear images

Summary In this paper, we have presented a new computer‐aided technique for automatic detection of nucleated red blood cells (NRBCs) or normoblast cell from peripheral blood smear image. The proposed methodology initiates with the localization of the nucleated cells by adopting multilevel thresholding approach in smear images. A novel colour space transformation technique has been introduced to differentiate nucleated blood cells [white blood cells (WBCs) and NRBC] from red blood cells (RBCs) by enhancing the contrast between them. Subsequently, special fuzzy c‐means (SFCM) clustering algorithm is applied on enhanced image to segment out the nucleated cell. Finally, nucleated RBC and WBC are discriminated by the random forest tree classifier based on first‐order statistical‐based features. Experimentally, we observed that the proposed technique achieved 99.42% accuracy in automatic detection of NRBC from blood smear images. Further, the technique could be used to assist the clinicians to diagnose a different anaemic condition. Resumo In this paper, we have presented an automated, efficient NRBC detection methodology for identification of different anaemic conditions from peripheral blood smear images. To achieve this goal, we have introduced a new approach for intensifying the visual quality of nucleated cells (WBCs and NRBC) resulting in the improved discriminating property between nucleated and nonnucleated cells. SFCM technique is implemented to segment the nuclea...
