Due to the fact that disc on top of which object was kept is also visible,the disparity changes in the object are not visible. However please note
that disc itself is visible as a ring at the lower part. To overcome this
difficulty we cropped the image to leave out the disc. Then the reconstruction
was done again.
THE IMPLICIT SURFACE (II)
Next, we cropped the image to remove the lower pixels showing the disc. Now the implicit surface generated was much better and resembeled the surface . The interior points are given a value 0 and hence they are also not plotted i.e. the central cavity is observed.
