41. Explain the working of Facebook face verification.

Working includes various steps:

• Firstly, Input. This firstly scans a wild form of photos with big complex data. This contains blurry images, images with high intensity and contrast.
• Secondly, Process. The process completes in four steps:
  • Firstly, detecting facial features
  • Secondly, aligning and comparing the features
  • Thirdly, representing the key patterns by using 3D graphs
  • Lastly, classifying the images based on similarity
• Thirdly, Output. The final result is a face representation, derived from a 9-layer deep neural net.
• Then, Training Data. There are more than 4 million facial images of more than 4000 people.
• Lastly, Result. Facebook can identify whether the two images represent the same person or not.
