Face recognition using a webcam and the use of this information, language, ready-made software, problems?

Question

Pattern recognition

1) Will any webcam work?
2) Is there a ready-made software?
3) By use, I mean that this information can be used in your programs, for example, is there a person in the database? Yes - you can use the computer, no - goodbye

Answer 1

if you can bring the face to the camera, and even position it - there is amateur software (such as homemade crafts www.softportal.com/get-23444-ctsfacefinder.html) , otherwise you need to cut it yourself based on OpenCV or other powerful libraries too https ://facedetection.com/software/
