Image Particle Analysis Image J Image Particle Analysis Image J Document Transcript

  •   Image particle analysis:  Open image or drag and drop.  There are two way to go for the particle analysis. ImageJ want either  the image is binary which can be done by     Result looks like  Created by Jyoti Mohanty 8/26/2008  Page 1   
  •     For our purpose the other way is the best. The threshold and then the  particle analysis  As shown below.  Created by Jyoti Mohanty 8/26/2008  Page 2   
  •   Choose the required level for threshold e.g. the white area.    Then go to particle analysis  Created by Jyoti Mohanty 8/26/2008  Page 3   
  •   Check the size.    One can play with the drop down called show  Created by Jyoti Mohanty 8/26/2008  Page 4   
  •   Repeat same thing for the black area by choosing the appropriate threshold.    Created by Jyoti Mohanty 8/26/2008  Page 5   
  •     In the  summary the total area in calculated for white or black areas. At the end  one has the white and black area counted and listed. By subtracting these two  added sum from the total picture area one gets the gray area. This procedure  should be repeated 4‐5times to get the average value and the standard  deviation.    Some play with 3D.  Created by Jyoti Mohanty 8/26/2008  Page 6
