Automatic Classification of Red Blood Cell Morphology Based on Quantitative Phase Imaging

Figure 6

Segmentation and extraction effect of RBCs in different imaging modes. The images in the first line are preprocessing results of BF, OL, DPC, QPI, and mesh, where A, B, and C are the spherocyte, echinocyte, and discocyte, respectively. The images in the second line are thresholding results processed by the Otsu method. The images in the third line are edge extraction results processed by thresholding results, where the extracted cell edges are marked with red points.
