flags to OFF and rebuilding, the error disappears. Also, the same cv::Mat can be used in different threads because the reference-counting operations use the architecture-specific atomic instructions. It takes the desired array size and type. Anyway to get around this without recompiling with cmake?

If you just store the lowest 8 (16) bits of the result, this results in visual artifacts and may affect a further image analysis. The size and type of the output arrays are determined from the size and type of input arrays.
