I am professor in Dental College,Rohtak,Haryana,India.I am analysing Dental
X-Ray by opening in Image J afterwards I select a rectangular area which is
put to plot profiler( short cut Alt+K) .In the plot again rectangular area
is selected and  plot profiler again utilised to generate plot of plot .this
procedure is repeated several times,and I could see plot of structures of
minus exponential values
upto 45.
