PNIPU: FrontArt Human Face Analysis Program

2022: Announcement of a program for analyzing the state of a person's face

Researchers from Perm Polytechnic developed that software will be able to analyze the condition of a person's face. Based on photographs and individual data , the software will track changes in the contour of the face and the shape of its individual parts, as well as the relief. skin The FrontArt program will assess the symmetry of the face, revealing dental and facial disorders. The data will be able to be used medical by ambulance staff in the diagnosis of acute cerebrovascular accidents () or strokes traumatic brain injuries, as well as, and. stomatologists surgeons beauticians The technology can be used by both doctors and patients themselves. have already Scientists received state a certificate of registration of the program. The project was implemented within the framework of the Strategy for Scientific and Technological Development. RUSSIAN FEDERATION This was announced on November 24, 2022 by representatives of the Polytechnic. Perm

According to the developers, as of November 2022, there is a trend towards the digitalization of clinical practice and the development of telemedicine consultations. The software product using a smartphone will allow the user to assess the change in the shape of the lips, nose, cheeks and cheekbones, the contour of the face, the relief of the eyelids, as well as the results of eliminating skin imperfections. 

For analysis, a person needs to take pictures of his face with a smartphone camera. Next, the software, using photogrammetry technology, builds a 3D model of the face in a virtual environment and determines reference points on the surface. Based on the mathematical algorithms we have developed, it calculates the parameters of the face: constitution, harmony, symmetry, severity of skin changes. According to the results of the assessment, a person receives a clinical opinion. It can be used in neurology to detect facial asymmetry in acute cerebrovascular accident. The program will also be relevant in cosmetology for the diagnosis of age and gravitational changes, as well as in orthopedic dentistry for the determination of aesthetic bite disorders. explained Ivan Shitoev, project manager, assistant of the Department of Computational Mathematics, Mechanics and Biomechanics of the Perm Polytechnic, director of the Yord Tech company

In particular, acute facial asymmetry can be a signal of both facial nerve damage and the development of an acute cerebrovascular accident in the pool of one of the internal carotid arteries or traumatic brain injury. In this case, urgent differential diagnosis of urgent lesions of the central nervous system should be carried out. The program will allow emergency medical personnel to diagnose at the initial stage, in conditions of shortage of time.

Unlike analogues, the development of scientists of the Perm Polytechnic is intended for the mass consumer. To do this, you need to install the application on your smartphone. 

The peculiarity of the development is that for the first time software for photogrammetric three-dimensional assessment of facial parameters will be implemented, which uses clinical algorithms for assessing disorders. This technology has not previously been used for living objects. The product will be able to become a full-fledged modular diagnostic tool.. narrated by a young researcher

The program includes an algorithm created by scientists for registering reference calculated points of a face with a fixed position, which is based on the location of bone structures. In addition, the product uses embossed and color characteristics of a three-dimensional object, unlike analogues that evaluate the parameters of a "flat" image. The program also does not require additional technical devices to be implemented. For November 2022, the prototype software is being tested in real conditions.
