lamm45	1f0bfc8d83	Fix angle discretization in Hough transforms In some situations the last value was missing from the discrete theta values. Now, the last value is chosen such that it is close to the user-provided maximum theta, while the distance to pi remains always at least theta_step/2. This should avoid duplicate detections. A better way would probably be to use max_theta as is and adjust the resolution (theta_step) instead, such that the discretization would always be uniform (in a circular sense) when full angle range is used.	2 years ago

Povilas Kanapickas	6a4c3b61e6	Improve doc of calcHist overload that accepts vectors It's not clear how ranges argument should be used in the overload of calcHist that accepts std::vector. The main overload uses array of arrays there, while std::vector overload uses a plain array. The code interprets the vector as a flattened array and rebuilds array of arrays from it. This is not obvious interpretation, so documentation has been added to explain the expected usage.	2 years ago

Vincent Rabaud	542b3e8a64	Fix harmless signed integer overflow. When computing: t1 = (bayer[1] + bayer[bayer_step] + bayer[bayer_step+2] + bayer[bayer_step2+1])G2Y; there is a T (unsigned short or char) multiplied by an int which can overflow. Then again, it is stored to t1 which is unsigned so the overflow disappears. Keeping all unsigned is safer.	3 years ago

Vincent Rabaud	d4741eece1	Fix H clamping for very small negative values. In case of very small negative h (e.g. -1e-40), with the current implementation, you will go through the first condition and end up with h = 6.f, and will miss the second condition.	3 years ago
