histogram of a surrounding sphere
Locked

Hi,In a 3D 8-bit stack (comes from tomography experiment), I would like to have for each point the histogram of the grey scale value of the surrounding voxels contained in a sphere (of 5 voxel radius for example) centered on the point.Any help is warmly welcome.Thank you

for each point, the coordinates (x, y, z) with its histogram, as text data.I know that could be quite heavy...

There's a plugin for that in http://rsbweb.nih.gov/ij/plugins/hough-circles.html However, that's only for 2D binary images, so it might only be useful as a guide. I hope that's useful, Pablo |

Hi,
You can use my ij3d API, here a simple plugin to do that (beware a lot of text !!) : compile it using -cp ij.jar and ij3d-bin.jar http://imagejdocu.tudor.lu/doku.php?id=plugin:morphology:3d_binary_morphological_filters:start Hope this helps, tell me if you need more explanations.

Hi,
You need first to rename your file to the same name as the class : HistoPixel3D_.java let's assume ij.jar and ij3d-bin.jar and the HistoPixel3D_.java file are in the same folder : javac -cp ij.jar:ij3d-bin.jar HistoPixel_.java use ; instead of : with Windows Thomas > Thomas,Thank you for your help!

So obvious... Thanks a lot, the plugin works perfectly!

yes, it actually is! I didn't see it that way, thanks... but knowing how to perform the norm of "tab" would be interesting all the same

Hi,
Yes a 3D mean filter, you can use the jni3d filter for faster filtering : http://imagejdocu.tudor.lu/doku.php?id=plugin:filter:3d_filters_with_jni:start for the "tab" you just add : float mean=tab.getMean(); or getSigma ... look at the API Thomas m000an ZH a écrit : > yes, it actually is!

You mean you want the average values in the 3D sphere for a series of points in a texfile ?
