It seems that a wrong variant name used in img_hash/src/radial_variance_hash.cpp:afterHalfProjections().

System information (version)

• OpenCV => 4.5.5
• Operating System / Platform => Windows 64 Bit
• Compiler => Visual Studio 2015

Detailed description

In img_hash/src/radial_variance_hash.cpp:afterHalfProjections(), there are some codes as:

for(int x = 0; x < D; ++x) { float const y = alpha*(x-xOff); int const yd = static_cast(std::floor(y + roundingFactor(y))); if((yd + yOff >= 0)&&(yd + yOff < input.rows) && (x < input.cols)) { projDown[x] = input.at(yd+yOff, x); pplPtr[k] += 1; } if ((yOff - yd >= 0)&&(yOff - yd < input.cols)&& (2yOff - x >= 0)&&(2yOff- x < input.rows)&& (k != init)) { projUp[x] = input.at(-(x-yOff)+yOff, -yd+yOff); pplPtr[k-j] += 1; } }

The bold and italic variant "yOff" seems wrong? And should it be "xOff"?
