Description (last modified by bdezonia) (diff)

Process > Binary > Make Binary does not work the same as IJ1 for all image types.

It works with Boats (1-bit black and white).
It fails with Organ of Corti (data is treated as a 8-bit Color hyperstack rather than a 1-bit hyperstack).
It fails with Clown (data is black and white but stays 8-bit rather than 1-bit)

It fails with a 32-bit version of Bridge. In IJ1 open bridge, change type to 32-bit, run Make Binary and its fine. In IJ2 open bridge, change type to 32-bit float, run Make Binary, and then all values are 255. Editing Brightness/Contrast to match IJ1's values before running the Make Binary command had no effect on results.

With commit 843ba423554ac55947b92a66721e95870e802cee all file types now becoming binary as needed.

However the issue of bridge being all 255's is not yet fixed. That may be a different bug altogether. Investigating.

The code that correctly handles the binary type tracking is slowing down harmonization of all 8-bit images. We'll need to find a more efficient way to handle this before the release.

  • Status changed from new to closed
  • Resolution set to fixed

The issue where a float version of the bridge is all 255 is an issue with thresholding. The IJ1 plugin is returning the image as all 255's. It uses thresholds to calc pixel values. I think we are not handling thresholds at all at the moment. Opening that issue as a new ticket.

Closing this ticket.
