    • this lib is great!:)
      I searched for a long time for some good libs which would be simple enough to get easily understood and this is it...
      Thx...

    Dlib is very helpful Library :) thank you :) . I did implement Face detection program , it takes 120 seconds(image size:1280x720) to detect one face. tried resizing the image , it picks up speed to some extent , can you tell me how do I increase the speed other than resizing the image . Iam working on a single image ,so i think threads are not of much use

      Did you enable SSE4 or AVX? You can do this by looking at the cmake
      options, either via ccmake or cmake-gui and setting SSE4 to on (or AVX
      if you have a CPU from about 2013 or later). That should make it
      faster. Or if you are rolling your own

      Also, shrinking the image should give a speedup proportional to the
      size reduction. So, for example, if you went from 1280x720 to 640x480
      it should be 4x faster. Is that what you observed?

      Cheers,
      Davis

    Thanks for the response :) , I am working on windows ,following the instructions I did enable the enhanced instruction set SSE2, but no change in time. I think I will have to go with resizing the image.

    Thank you for your time :) . have a good day .

      No problem :)

      Did you turn on SSE4 or just SSE2?

      Cheers,
