What Is Dlib in Python?

According to dlib's github page, dlib is a toolkit for making real world machine learning and data analysis applications in C++. While the library is originally written in C++, it has good, easy to use Python bindings. I have majorly used dlib for face detection and facial landmark detection.

What is dlib used for?

What is Dlib? It's a landmark's facial detector with pre-trained models, the dlib is used to estimate the location of 68 coordinates (x, y) that map the facial points on a person's face like image below. These points are identified from the pre-trained model where the iBUG300-W dataset was used.

Is dlib a OpenCV?

1 Answer. I have used both OpenCV and dlib extensively for face detection and face recognition and dlib is much accurate as compared to OpenCV Haar based face detector. ( Note that OpenCV now has a DNN module where we get Deep Learning based Face Detector and Face Recognizer models. )
