Measuring Size

Radha Narayanan
I am interested in using ImageJ for analyzing the size of  
nanoparticles in a TEM image.  I would like to measure the scale bar  
which is a certain amount of pixels.  I would like to use threshold to  
highlight all of the particles in an image and obtain the size  
distribution data based on the number of pixels and the corresponding  
histogram.  I would really appreciate it to know how to do this in  
ImageJ.

Thanks,
Radha

Re: Measuring Size

s c narula
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.
Ihope this might help you
