Image sizes for dsPreProcessBatchInput

[Egorundel]

static void dsPreProcessBatchInput(const std::vector<cv::Mat*>& cvmats, cv::Mat& batchBlob,
                                   const int& processingHeight, const int& processingWidth,
                                   const int& inputH, const int& inputW)
{
    ...
}

Hello, what image sizes are fed into this function?
My neural network takes an image of size 512x512 as input.
I understand that in this function they need to be set as inputH and inputW?
If I'm right, what are the dimensions of processingHeight and processingWidth?
