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 2015-05-28 19:33:21 +03:00

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.

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.

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.

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.

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.
