mvukad	695e33b25b	Fix missing format when writing Algorithm-based objects Added a writeFormat() method to Algorithm which must be called by the write() method of derived classes.	9 years ago
Philip	1ba2286c6d	fix uninitialized matrix in EM::predict fixes #5443 fixes #5443	9 years ago
Dikay900	4f3b58d1e7	fix reshape call not being an inplace method fixes #5853 #4740	9 years ago
Tian Zhi	f0434d60b0	fixed the type inconsistent with document. Document say probs will have CV_64F type. But in effect, it has CV_32F type. http://docs.opencv.org/3.0.0/d1/dfb/classcv_1_1ml_1_1EM.html#a2ea7da92a75bc7a7d665c241f547b9b9	9 years ago
Miguel Algaba	b71a27b96c	Assert fix: allow one cluster as valid parameter	10 years ago
art-programmer	e0ef293645	Update em.cpp Fix a bug. When reading from a saved model, function decomposeCovs() will be called. And if covMatType is COV_MAT_DIAGONAL, covsEigenValues is computed using SVD and eigen values are sorted so that the order of eigen values is not preserved. This would lead to different result when calling function predict2. This issues is discussed here: http://stackoverflow.com/questions/23485982/got-different-empredict-results-after-emread-saved-model-in-opencv.	10 years ago
Vadim Pisarevsky	052593c760	1. Input/OutputArray optimizations; 2. Algorithm::load/save added (moved from StatModel) 3. copyrights updated; added copyright/licensing info for ffmpeg 4. some warnings from Xcode 6.x are fixed	10 years ago

Vadim Pisarevsky	f9fc180e1a	fixed tickets #1117 and #954	14 years ago
Vadim Pisarevsky	20aca7440f	a lot of small corrections to bring down the number of undocumented functions, reported by the script; added em.cpp sample	14 years ago
Maria Dimashova	9e21f06404	replaced M_PI by CV_PI	14 years ago

Vadim Pisarevsky	65a7f13af3	replaced alloca() (a.k.a. cvStackAlloc) with AutoBuffer or vector() everywhere. cvStackAlloc() is still defined, but we do not need alloca() anymore to compile and run OpenCV (fixes #889 and may be some others)	14 years ago
Vadim Pisarevsky	bc21cc6fe9	revert to using fixed RNG in EM, otherwise the algorithm becomes non-deterministic and the test fails sometimes. in the meantime, EM needs to switch to more robust cv::kmeans instead of CvEM::kmeans.	14 years ago
