I need MATLAB code to extract and compare facial features

I working in user-based authentication based face biometric.

I need a matlab code for extarct face features and evalauate the matching scores of faces

Hi Alawi,

I understand that you want to extract facial features from an image/video and match the similarity score of the faces in the input with some reference faces. You can follow the following steps to achieve the same:

1. Using MATLAB's inbuilt face detector, detect faces in both the reference and query images. This will provide the bounding boxes or regions of interest (ROIs) where faces are located.
2. For each detected face in the reference and query images, use the face recognizer to extract facial features. This step converts each face into a feature vector that represents its unique characteristics.
3. Compare the facial features of the query image with the reference images to calculate similarity scores. This can be done by comparing the feature vectors using a distance metric such as Euclidean distance or cosine similarity.

You can refer to the following MathWorks documentation to understand how to use face detector and extract facial features:

I hope this helps.
