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.

Vadim Pisarevsky 3c51fdffac Merge pull request #3849 from Dikay900:fix_tilted_features_crash 2015-03-24 15:19:13 +00:00
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.

Guo Yejun 595ec6b852 correct the size of buf which holds integral sum/sumsq 
layer_dy is not initialized correctly, it results in a small height
of the buffer, and so memory write is out of range in cv::integral.

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.

IPP can be switched on and off on runtime;

Optional implementation collector was added (switched off by default in CMake). Gathers data of implementation used in functions and report this info through performance TS;
