Hi, I get strange results when I use the houghtf function from the image package (tested with version 1.0.10 on windows and 1.0.12 on Ubuntu) with GNU Octave Version 3.2.4.
For example, when I run the following code several times in a row, I get different results even though the input should be exactly the same as far as I can tell. %%% testing.m %%%%%%%%%%%%%%% clear I J I = zeros(100,100); I(30,:) = 1; I(:, 65) = 1; I(35:45, 35:50) = 1; for i = 1:90, I(i,i) = 1;endfor J = houghtf(I); max(max(J)) plot(max(J)); %%%%%%%%%%%%%%%%%%%%%% The reported max values seems to increase almost every run and the shape of the plot differs as well. Sometimes only the scale of the plot is changed but other times the shape changes drastically between different runs. This is the behavior when the image size is set to 100x100 and most other image sizes I have tried to use. If the image size is changed to 100x150 as in the test code, the result from the houghtf function seems to be identical every time.
