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

Figure 8

Morphological analysis of the different shapes of RBCs in BF and QPI. (a) RBC BF image. (b) RBC QPI image. (c) Local image as shown in the red box of (a). (d) Local image as shown in the green box of (b). (e) BCs of the three shapes of RBCs in BF and QPI and their mesh form, where the white dots of A, B, and C are the equally spaced sampling points of cell boundary, red marks “+” represents positive value of BC, red marks “−” represents the negative value of BC, and N is the number of negative values of BC mentioned in equation (4).
