I try to build the sample code in tutorial Similarity check (PNSR and SSIM) on the GPU , and there are many error like gpu-basics-similarity.cpp 328 error: no match for ‘operator-=’ in ‘sigma1_2 -= mu1_2’

I try to trace the gpumat.hpp and gpu.hpp, it seems like there is really no implement of operator like +, -, *, +=, -=, ...

Is this a bug or something I misunderstand?

It seems like it's bug in documentation and sample code. There are no overloaded operators +,-,+=,etc for GpuMat.

Use gpu::subtract(b.sigma1_2, b.mu1_2, b.sigma1_2, stream);

Should I issue this to code.opencv.org?

Yes. Documentation error is still an error and need to be fixed.
