Detailed Description

Check CPU features (hardware capabilities).

The example below shows how to check or get CPU capabilities.

#include <visp3/core/vpCPUFeatures.h>

int main()
{
  std::cout << "checkSSE2: " << vpCPUFeatures::checkSSE2() << std::endl;
  std::cout << "CPU info: " << vpCPUFeatures::printCPUInfo() << std::endl;
  return 0;
}
