Suleyman TURKMEN	22eb91a7e0	Update hough.cpp	2 years ago
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

Pierre Chatelier	ef6f421f89	Merge pull request #21677 from chacha21:rectangle_intersection * better accuracy of _rotatedRectangleIntersection instead of just migrating to double-precision (which would work), some computations are scaled by a factor that depends on the length of the smallest vectors. There is a better accuracy even with floats, so this is certainly better for very sensitive cases * Update intersection.cpp use L2SQR norm to tune the numeric scale * Update intersection.cpp adapt samePointEps with L2 norm * Update intersection.cpp move comment * Update intersection.cpp fix wrong numericalScalingFactor usage * added tests * fixed warnings returned by buildbot * modifications suggested by reviewer renaming numericalScaleFctor to normalizationScale refactor some computations more "const" * modifications as suggested by reviewer	3 years ago
