Fixes Coverity CID 709286: Division or modulo by zero (DIVIDE_BY_ZERO)
Assigning: "maxVal" = "this->max()".
On this path, function call "this->max()" has return value of 0
78 int64_t maxVal = max();
...
Division by expression "maxVal" which may be zero has undefined behavior
86 val = m_correlationVector[x]/double(maxVal)*img.height();
