if (area >= 30 &&
std::abs(1 - ((double)rect.width / (double)rect.height)) <= 0.2 &&
std::abs(1 - (area / (CV_PI * std::pow(radius, 2)))) <= 0.2)
What I want to be translated is the std::abs
and the CV_PI * std::pow
.
I've search the net for std::abs
equivalent to java and failed to find any. Please help. Wasn't able to search for CV_PI * std::pow
since I can't still find the std::abs
.
Look at the Math
class.
https://docs.oracle.com/javase/7/docs/api/java/lang/Math.html
Math.PI
Math.pow(...)
Math.abs(...)
etc.
