Face Feature Vector Construction

A non-transitory computer readable medium, comprising computer code to:

• obtain a landmark image for a first face in a first image, the landmark image identifying a plurality of aspects of the first face;
• generate a normalized landmark image based, at least in part, on the landmark image;
• generate a warped landmark image based, at least in part, on the normalized landmark image;
• generate a first shape model feature vector based, at least in part, on the landmark image;
• generate a second shape model feature vector based, at least in part, on the landmark image;
• generate a first texture model feature vector based, at least in part, on the normalized landmark image;
• generate a second texture model feature vector based, at least in part, on the warped landmark image;
• combine the first shape model feature vector, the second shape model feature vector, the first texture model feature vector and the second texture model feature vector to form a first face feature vector;
• store the first face feature vector in a storage device;
• retrieve the first face feature vector from the storage device;
• retrieve a second face feature vector form the storage device, wherein the second face feature vector corresponds to a known person;
• compare the first face feature vector and the second face feature vector to generate a similarity value;
• determine the first face corresponds to the known person if the similarity value is greater than a specified amount;
• and
• determine the first face does not correspond to the known person if the similarity value is not greater than the specified amount.
