I have annotation data (1,18) joints (example image): enter image description here How can I normalize these features vector like they did. each points have (x,y) annotated coordinates.

    Since the coordinates of the annotated joints are labeled in the image
space, poses which are very similar to each other might appear in different parts of 
the image, resulting in input vectors with very different values. We, thus, normalize 
them using the following procedure: first we find the center of the torso (C T ) by 
averaging the coordinates of the neck and at least one of the shoulders and hip joints; 
the pose is then translated to the obtained 2D point and finally scaled by the distance 
between the neck and C T .
