Error creating thumbnail: Unable to save thumbnail to destination
Output Gray Image
Example
CuviImage gimg = cuvi::io::loadImage(path), gout;
//Convert to gray-scale using standard coefficients
cuvi::colorOperations::rgb2gray(gimg,gout);
//Convert to gray-scale using custom coefficients
CuviScalar coeffs(0.33, 0.33, 0.33);
cuvi::colorOperations::rgb2gray(gimg,gout, coeffs);
