Julien Nabet	a29c814bd8	cppcheck: fix some reports All of these: (performance) Prefer prefix ++/-- operators for non-primitive types. [modules/calib3d/src/fundam.cpp:1049] -> [modules/calib3d/src/fundam.cpp:1049]: (style) Same expression on both sides of '&&'.	9 years ago
Artyom Lebedev	8ceac4b73b	Update fisheye.cpp Fix for inconsistent asserts in cv::fisheye::initUndistortRectifyMap() which prevents from passing empty matrices in debug build (which is allowed according to the code bellow the asserts and the docs).	9 years ago

Alexander Karsakov	e784ea7178	Fixed getSubset method to support Nx3 1-channel matrices as input (3xN 1-channel matrices doesn't supported at all).	9 years ago
Alexander Karsakov	0c9c7d5f3b	Added test for checking that solvePnPRansac accepts vector<Point3f> and Nx3 1-channel or 1xN/Nx1 3-channel matrices as input.	9 years ago
Alexander Karsakov	6e22020dad	Fixed pnpTask: don't copy inliers vector in case it's empty.	9 years ago
Kai Hugo Hustoft Endresen	551b5d3e1a	StereoSGBM.cpp - use SSE2 for pass 2 using MODE_HH With a test image set of 2800x1400 bytes on a Intel Core i7 5960X this improves runtime of MODE_HH with about 10%. (this particular replaced code segment is approx 3 times faster than the non-SSE2 variant). I was able to reduce runtime by 130 ms by this simple fix. The second part of the SSE2 optimized part could probably be optimized further by using shift SSE2 operations, but I imagine this would improve performance 10-20 ms at best.	9 years ago

Pavel Rojtberg	60c06e551a	calibrateCamera: do not require rvec and tvec to be vector<Mat> if they are not we also do not need to allocate a local copy of the rvec and tvec	9 years ago
Pavel Rojtberg	205775ed52	calibrateCamera: only allocate and compute rvecs, tvecs when needed also replace C defines with C++ enums	9 years ago
Pavel Rojtberg	b5ddaae427	calib3d: add CALIB_USE_LU to use LU decomposition in solver	9 years ago
Pavel Rojtberg	4c251bd260	CvLevMarq: add solve method to interface	9 years ago
Pavel Rojtberg	22b64e2c28	CvLevMarq: remove fixed rows instead of setting them to zero use the same approach like in fisheye calibration: instead of setting masked out rows to zero, remove them from the equation system. This way JtJ does not become singular and we can use the much faster LU decomposition instead of SVD. This results in a speedup of the Calibrate unit tests of 3x-10x.	9 years ago
