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.
