Partial Face Recognition

Until now, face recognition systems have treated a face as a homogeneous entity. Face Forensics Partial Face Recognition technology is unique in that it takes just part of a face and matches it against the same parts in a database of complete faces. This is of real value in forensic and investigative environments where only part of a face may be available, for example surveillance images, body parts after an explosion, burn victims, a photograph where only part of a face is visible, etc.
Partial face recognition is a module within the Face Forensics face recognition application. All the functionality of full face recognition is available to recognize and match the partial face. Selecting “Partial face” on a pull-down on the Face Screen displays a facial template.

A frontal shot is taken of the facial part.  This image is either pasted or drag-and-dropped onto the facial template. The template itself is a computer-generated generic face.

Once the image is placed over the relevant area of the template it will have to be resized to match the size of the template. The template itself can then be adjusted to change the distance between the eyes, and the position of the nose.  Once the partial face is deemed to be in the most realistic position the eye centres are manually selected as shown here:
The match list above shows the results of a search against the partial face on the template. The eyes on the template have been moved slightly apart to match the face being searched. The template is shown first, while the next two images are of the same person as the partial face.

Face Forensics Partial Face Recognition works with all major databases, including Oracle, SQL-Server, DB2, and MS-Access. Databases are accessed in read-only mode - the system keeps its own database of encode strings so data integrity is not compromised. Face Forensics Face and Partial Face Recognition are available in both 32-bit and 64-bit versions, so extremely large databases can be accessed. The interface can be readily switched to any language. Face Forensics can search static images, real-time video, video files, and websites. Search speeds are extremely fast – because the encodings are held in memory, in excess of 1m records per second can be searched. System Requirements FaceForensics is available as an application or .NET SDK. It runs under Windows XP, Vista, and Windows 7 (in 32-bit and 64-bit versions). It will access Oracle, SQL Server, DB2, and MS Access databases. An evaluation version is available.
