Hi @Chandra Shekhar,

To extract the face part in an image, "vision.CascadeObjectDetector" might help you in getting started. The cascade object detector uses the Viola-Jones algorithm to detect people’s faces, noses, eyes, mouth, or upper body.

Refer to the following documentation for better understanding: https://www.mathworks.com/help/vision/ref/vision.cascadeobjectdetector-system-object.html

Hope this helps!
