I have a structure the reuslt of hough table, with 1200 values like theta, rho etc.
I made a projection in theta values to show the distribution of the theta.
So i puted on X-axis the agle range from -90:90 and ploted in histogram. I was expecting to see two gaussian curves with negative and possitive theta.
The result is this:
I want to find the threshold between the two curves, i suppose its near -10
I tried Otsu threshold with graythresh function, but it gives a normalized value equals to 0,453, because otsu gives result in [0,1] range.
Any idea how to find the threshold?
