(English Abstract) |
Cells in a culture process transform with time and produce many overlapping cells in theirvicinity. We are interestedin a separation algorithm for images of overlapping cells taken using afluorescence optical microscope system during acell culture process. In this study, all cells are assumed to havean ellipse-like shape. For an ellipse fitting-based method, an improved least squares method is used by decomposing the design matrix into quadratic and linear parts for the separation of overlapping cells. Through various experiments, the improved least squares method (numerically stable direct least squares fitting [NSDLSF])is compared with the conventional least squares method (direct least squares fitting [DLSF]). The results reveal that NSDLSFhas a successful separation ratio with an average accuracy of 95% for two overlapping cells, an average accuracyof 91% for three overlapping cells, and about 82% accuracy for four overlapping cells. |
