In the attempt to reduce the computation time, image
segmentation on image with 8×8 image cells is performed as
shown in Fig. 8. Eventually, the computation takes about 3
minutes which is less than the previous segmentation about
half of the time. This indicates increasing number of cells
helps to reduce the computation time as the area of an image cell has become smaller despite more cells is added for first
stage segmentation. Small size of image cell to some extend
can help to reduce the occurrence of important boundaries to
be missed out during segmentation process. However, small
image cell is not suitable for image with large objects in it.
This leads to the segmentation on the image cells is
performed unnecessary. Fig. 8 shows the segmentation result
when the number of cells is increased
