How do you extract face features?
Facial feature extraction is the process of extracting face component features like eyes, nose, mouth, etc from human face image. Facial feature extraction is very much important for the initialization of processing techniques like face tracking, facial expression recognition or face recognition.
How does facial recognition collect data?
Face recognition systems use computer algorithms to pick out specific, distinctive details about a person’s face. These details, such as distance between the eyes or shape of the chin, are then converted into a mathematical representation and compared to data on other faces collected in a face recognition database.
What is face detection used for?
In face analysis, face detection helps identify which parts of an image or video should be focused on to determine age, gender and emotions using facial expressions.
How to extract a face from an image?
As described above, I iterate all faces, calculate the confidence of detection and if it is more than 50%, I extract the face. Notice the line frame = image [startY:endY, startX:endX]. It extracts the face from the image.
How is feature extraction from a face image using CNN?
Concerning your issue about the feature extraction from a face image using cnn. Convolutional Neural Networks allow us to extract a wide range of features from images. Turns out, we can use this idea of feature extraction for face recognition too!

If you have found a bug are having issues with the Extraction process not working, then you should post in the Extract Support forum.
Do you need to extract faces for conversion?
Whilst the extracted faces are not required for convert (only the alignments file is), it is useful to have them so that we can clean up our dataset for the conversion process. Similarly, if extracting faces for a training set, then the original alignments file is not actually required.
