[Octave-bug-tracker] [bug #38464] image: regionprops misses some pixels?

[Carnë Draug]

Follow-up Comment #5, bug #38464 (project octave):

@JuanPi

_So Matlab also misses some of the points?_

No. Matlab's bwlabel doesn't miss any of the points, and neither does Octave.
The bwlabel function will label any non-zero pixel in the image with a
positive number. We can confirm that it does not miss any of the points with
the following:


lblNodes = bwlabel (imgNodes);
isequal (lblNodes > 0, imgNodes);


While the bwlabel function has changed since this report, the above still
returns true when using the lblNodes variable present on the bwlabel_miss.mat
file.

It is possible that bwlabel may be labeling two separate objects as being the
same, but it's certainly not missing any pixel.
