Alexander Alekhin	323e24e3ef	change links from samples/python2 to samples/python	9 years ago
Ariel Bernal	5c8683139f	Fix for #5710 . OpenCL HOG Object detect assigns the wrong SIMD size. In oder to guarantee SIMDness between the two compilation steps we choose the highest SIMD size that is optimized in the kernel for the first step.	9 years ago
Maksim Shabunin	6e9d0d9a0c	Visual Studio 2015 warning and test fixes	9 years ago
Dikay900	7b0b12de58	appropriate logic behind last accepted stage when rejectingLevels is true	9 years ago
Pavel Vlasov	e837d69f8f	IPPInitSingelton was added to contain IPP related global variables; OPENCV_IPP env var now allows to select IPP architecture level for IPP9+; IPP initialization logic was unified across modules;	9 years ago
Pavel Vlasov	62854dcc0d	Enables support of IPP 9.0.0; HAVE_IPP_ICV_ONLY will be undefined if OpenCV was linked against ICV packet from IPP9 or greater. ICV9+ packets will be aligned with IPP in OpenCV APIs This will ease code management between IPP and ICV	9 years ago
Alexander Alekhin	7213e5f68a	ocl: correct disabling of OpenCL code	9 years ago
Alexander Alekhin	caaf60ba00	remove bindings generation for DetectionBasedTracker	10 years ago
Vadim Pisarevsky	882c0321f4	clip the found objects in HOG as well (http://code.opencv.org/issues/3825 ); added test to check CascadeClassifier on small images (http://code.opencv.org/issues/3710 )	10 years ago
Vadim Pisarevsky	8c3c6b31fc	make sure the returned rectangles are inside the image (http://code.opencv.org/issues/3136 )	10 years ago
Vadim Pisarevsky	5a94a95fbf	improvements in Haar CascadeClassifier: 1) use CV_32S instead of CV_32F for the integral of squares (which is more accurate and more efficient); 2) skip the window if its contrast is too low	10 years ago

David Hirvonen	cab0ecdf19	Avoid clearing HaarEvaluator::tofs variable (introduced `fb8478eb7b`) in HaarEvaluator::setImage(...) since it won't be recomputed by HaarEvaluator::computeOptFeatures() for cases where the input image dimensions and requested search scales are the same as the previous. If none of the above change then it should be correct, and if they do change it will be computed correctly inside HaarEvaluator::computeOptFeatures() (in commit `952f9dbe62`) I'm guessing there is a unit test for this that needs to be called 2x with the same image and search parameters (or another image with the same size) to illustrate the problem.	10 years ago
Michaël Sdika	ab40c2acf7	added the signedGradient varaible to the HOGDescriptor class. when true, use signed gradient for the angular histogram computation. default to false for backward compatibility.	10 years ago

Dikay900	952f9dbe62	initialize tiltedOffset variable at correct location do not use this variable if it is not an tilted feature	10 years ago
Yan Wang	433c3da7cf	Optimize the performance of cascade OpenCL kernel. 1. Use built-in mad() instead of += and . 2. For stump stages, if weight.z == 0, avoid unnecessary calculation because some features only have 2 rectangles.. It could improve OCL_Cascade_Image_MinSize_CascadeClassifier.CascadeClassifier/ about 10% mean values. Signed-off-by: Yan Wang <yan.wang@linux.intel.com>	10 years ago

Yan Wang	efa84d8225	Use preprocessor for constant values in OpenCL kernel instead of the parameter variable. It could improve the performance of OCL_Cascade_Image_MinSize_CascadeClassifier.CascadeClassifier/*. Especially, OCL_Cascade_Image_MinSize_CascadeClassifier.CascadeClassifier/15 OCL_Cascade_Image_MinSize_CascadeClassifier.CascadeClassifier/16 could be improved about 2% in Intel platform.
