    Facial Recognition Algorithm: How it Works?

    As a human, we do facial recognition every day, probably for us, it is not a hard task at all because it almost a daily routine habit for us but for a computer system it is a complex job.

    So step by step we will try to understand the algorithm of facial recognition in simple language.

    First: It requires photos or videos in which you appeared. It won't be a concern if it's you only who's there in the picture or if it's a group photo along with your friends.

    With the facial recognition tool, your image will be cropped up to your face only. This is just like when you are clicking profile image.

    Second: In this step, facial recognition tool takes the measurements of your face which includes both eyes, size of chin, forehead, nose and it can also recognize your facial landmarks.

    The algorithm of the tool can also analyze the features of cheekbones and jaw. Facial landmarks could be any lines, scar, mole, etc. on your face. Some best tools in business can define 68 landmarks.

    Third: Your facial signature is combined with a mathematical formula, deep learning concepts, and Convolutional Neural Networks for accurate results.

    A recognition test runs in the database of familiar faces which could be in a police or military database or any other source.

    Convolutional neural network emerges as far better than the traditional algorithm of facial recognition.


    Facial recognition and face detection are two different streams but for the last two decades, both are at their peak.

    Just not for law enforcement or secret services but also for the corporate. Above mentioned open-source tools for facial recognition can definitely add appropriate measures to the security of your business.
