WebAll cells have a cell membrane that separates the inside and the outside of the cell, and controls what goes in and comes out. The cell membrane surrounds a cell’s cytoplasm, which is a jelly-like substance containing the cell’s parts. Cells contain parts called organelles. Each organelle carries out a specific function in the cell. WebHowever, the models proposed in Chapter 3 and 4 extracts the manually selected features for the cytoskeleton quantification. Those features may be too simple to fully deliver the information contained in the cytoskeleton structure. Therefore, an automated analytical model is needed for further studies.
