Hello,
I'm contacting you because I'm having trouble with the Imagej software. I have to characterize the fiber microstructure by finding their orientations. When I use OrientationJ I get a curve that gives me the distribution of angles. I would like to trace the fibers obtained on the image. How to do ? Thank you in advance. -- ImageJ mailing list: http://imagej.nih.gov/ij/list.html |
Good day,
you write: "I have to characterize the fiber microstructure by finding their orientations." "When I use OrientationJ I get a curve that gives me the distribution of angles." Finding fiber orientations and getting their orientations appears related. AFAIK, OrientationJ is not for tracing. Fiber tracing is quite different from getting fiber orientations. Please be more specific and post a typical image with detailed explanations of what you like to determine.

In fact, I would like to find the preferential orientations and draw them on the image.
I attach you the image to study. ________________________________ De : ImageJ Interest Group <[hidden email]> de la part de Herbie <[hidden email]> Envoyé : mardi 10 avril 2018 08:25 À : [hidden email] Objet : Re: OrientationJ Good day, you write: "I have to characterize the fiber microstructure by finding their orientations."

Good day,
attached please find the "Orientation Salience"-analysis that I've made from the pre-processed sample image. (Actually, the pre-processed image is DC-free, i.e. a 32bit bipolar image.) The dominant orientation is at 133.5 degrees. (Zero degree is horizontal and the angle increases counter-clockwise.) Now please tell us exactly what you like to see as a result image. Do you want to see the filtered image with only the dominant orientation?

Thank you very much. Yes that's exactly what I want to see and I would also like to know how you went about finding this result.

"Orientation Salience"-analyses are described in this report:
<gluender.de/Writings/WritingsTexts/WritingsDownloads/2013_Orientation.zip> Please note that the report doesn't deal with the highpass filtering that I've applied to your image in order to remove low frequency fluctuations of your sample image. As described in the report, "Orientation Salience" depends not only on the geometric orientation of the pictorial structures but also on the contrast of the structures! If you need this analysis for a few images only, you may send them to me offlist and I'll return the results.

How did you do to have a more resolute image. What constant values did you apply to which variables?
I work on the quality of the image but I am not satisfied. ________________________________ De : Herbie <[hidden email]> Envoyé : mercredi 11 avril 2018 09:38 À : Ndeye Birima Mbaye; [hidden email] Objet : Re: OrientationJ "Orientation Salience"-analyses are described in this report: <gluender.de/Writings/WritingsTexts/WritingsDownloads/2013_Orientation.zip> Please note that the report doesn't deal with the highpass filtering that I've applied to your image in order to remove low frequency fluctuations of your sample image.
