Boost rng vs OpenCV rng vs c++11 std::random?

这只是一个简单的问题，我需要一些意见。

我同时使用boost和OpenCV，我想生成一个随机数。哪个更好使用:boost::random::uniform_int_distribution (boost随机整数生成器)或cv::RNG ?

我写了这个:

// OpenCV RNG:
cv::RNG rngCV(cv::getTickCount());
int randInt = rngCV.uniform(0, 100); // generates integer number in [0, 100)
std::cout << "cv::RNG: " << randInt << std::endl;
// Boost RNG:
boost::random::mt19937 gen(static_cast<unsigned int>(std::time(0)));
boost::random::uniform_int_distribution<> rngBoost(0, 99);
int randInt2 = rngBoost(gen);
std::cout << "boost::random: " << randInt2 << std::endl;
// c++11 random
std::random_device rd;
std::default_random_engine el(rd());
std::uniform_int_distribution< int > unif_distr(0, 99);
int randInt3 = unif_distr(el);
std::cout << "std::random: " << randInt3 << std::endl;
