Package: octave-image
Version: 1.0.13-1
Severity: normal
hough_line() function returns different results between calls on the same image. Following code demonstrates this:
img = zeros(10);
img(5, :) = 1;
[h1 r1] = hough_line(img);
hough_line(img);
hough_line(img);
[h2 r2] = hough_line(img);
h1 - h2
h1 - h2 should naturally return 0 in all places but it often results quite large non-zero values. If this doesn't happen, run that code again and at some point this should return non-zero result.
This applies also to testing/unstable version of octave-image.
