Any ShapeFilter / IJBlob plugin tutorials? Wrong Image Format error

[aryrupp]

Hi all,
I am new to ImageJ and have been struggling for days now on to make Shape
Filter plugin work. The only tutorial I could find was programming-based -
skills I don't have. Could anyone briefly summarize the steps to obtain
results from this plugin? I couldn't find detailed information anywhere.

I will also mention I have been converting Tiff pictures into Binary using
FIJI Binary tools. Pictures seem to be properly converted and other
measurements work fine. When using Shape Filter plugin, I can preview the
Convex Hull polygon outlines, which would tell me the picture was properly
identified as a binary image. However, I am not able to export any measured
parameters and  receive the exception error message
"java.lang.IllegalArgumentException: Wrong Image Format. IJ Blob only
supports 8-bit, single-channel binary images".

Besides, it seems the plugin favors pictures with black background. When
proceeding the exact same steps with the white background inverse, I can't
even get to the point of previewing the Convex hull polygon.

Any help on this matter would be greatly appreciated!

Hi Ariana,

I am not sure if Thorsten Wagner (the author and maintainer of IJBlob
and the Shape Filter plugin) is following this mailing list.

You might have more luck mentioning @twagner on the forum:

http://forum.imagej.net/

Also, it will certainly be helpful if you can add an example image to
your forum post, then others will more likely be able to provide useful
advice.
