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.
