the functions where IPP was disabled: Sobel, Scharr, medianBlur, GaussianBlur, filter2D, mean, meanStdDev, sum, minMaxIdx, sort.
opencv_coresize is reduced by ~2Mb (19 down to 17),opencv_imgprocsize is reduced by ~24Mb (45 down to 21); other modules did not change, but they are much smaller than core and imgproc.The patch should not affect OpenCV performance much, since each of those functions is either very fast as-is, or optimized with SIMD instructions, or both.
cv::filter2Duses IPP-optimized DFT, so the performance should not drop either.
