Identification of the lipid droplets inside an N. oculata cell: (a) A 3D rendered iso-surface of RI distribution of the cell. (b) Cross-sectional images of different axial planes. (c) The identified lipid regions based on the RI threshold n > 1.46. The yellow curves indicate the cell boundaries. (d) The emulated fluorescence-like images generated from the identified lipid regions. (e) The fluorescence images of the same cell stained with Nile red dye.
