2014-10-19 21:14:20 -0600 commented question OpenCV and MPI

It seems that OpenCV is aimed at systems that are single boards, are there aspects of OpenCV that would make sense to parallelize with MPI?

It looks like the OpenCV is currently implemented with OpenCL. Why not MPI? I'm considering implementing a version with MPI.

Thanks!

2013-03-07 21:32:56 -0600 asked a question OpenCV latentSVM detector too slow

I'm using the OpenCV latent SVM detection with the sample code openCV and self-converted bicycle.xml to test a single image bike.img, which has a size of about 500x300. It takes ~11 seconds to complete this detection on my laptop.

Is it too slow? Has anybody tried this? Or am I making something wrong.

I can send the code, img and model files if you would like to help. Thank you very much.

2013-01-26 14:08:48 -0600 asked a question CV_WRAP and CV_EXPORTS_W

What's the meaning of these two keywords?

An example:

struct CV_EXPORTS_W HOGDescriptor { public: enum { L2Hys=0 }; enum { DEFAULT_NLEVELS=64 };

CV_WRAP HOGDescriptor() : winSize(64,128), blockSize(16,16), blockStride(8,8),
    cellSize(8,8), nbins(9), derivAperture(1), winSigma(-1),
    histogramNormType(HOGDescriptor::L2Hys), L2HysThreshold(0.2), gammaCorrection(true),
    nlevels(HOGDescriptor::DEFAULT_NLEVELS)
{}
