How can a 3 element vector constructer be multiplied by a Mat in OpenCV? I tried the following but it throws an error:
cv::multiply(src, cv::Vec<_Tp, 3>(2.0, 1.0, 1.0), src);
It gives the following error:
OpenCV Error: Assertion failed (src2.type() == CV_64F && (src2.rows == 4 || src2.rows == 1)) in arithm_op, file /Users/abhishek/Documents/OpenCV-2.4.3/modules/core/src/arithm.cpp, line 1275

Have you tried:
cv::multiply(src, cv::Scalar(2.0, 1.0, 1.0), src);
