Revision history [back]

I'd like to increase the amount of memory used in the training using opencv_traincascade, i tried to add precalcValBufSize and precalcIdxBufSize parameters but no thing seems to be changed my machine is 64GB ram and running linux OS when i see the consumption of training its always around 7.5 GB no changed occurred after adding the parameters although i see PrecalcValBufSize and precalcIdxBufSize in the terminal has been set to a value before it enters the stage. Any thoughts?
