Vietnamese people master AI technology, confidently reaching the world

(Dan Tri) - It takes less than 1.5 seconds to search and identify a face at an angle among 12 million people, Viettel AI's face search and recognition technology is in the top 4 in the world, according to NIST's evaluation results.

According to the results of the FRTE (Face Recognition Technology Evaluation) 1:N Identification assessment published in February 2024 by the US National Institute of Standards and Technology (NIST), the Center for Data Services and Artificial Intelligence (Viettel AI) is in the top 10 in 5 out of 8 categories, of which it is ranked 4th in the world and 1st in Vietnam in the Mugshot Profile 90 category (face recognition at an angle). Overcoming difficulties to build comprehensive face recognition technology The FRTE assessment includes 8 categories, which are 8 problems of searching and recognizing faces in different conditions such as non-frontal photos, low resolution, poor lighting, etc. Each category is a difficult problem because such non-ideal conditions affect the accuracy and performance of the technology. With the Mugshot Profile 90-degree category, the faces are rotated horizontally at a 90-degree angle, leaving only half of the face for recognition. At that time, the facial features are also reduced by half, making it easy to misidentify or not be able to identify. Not only that, the NIST assessment sets many strict standards to find a method that is both accurate in recognition and optimal in processing time, ensuring high practical applicability. The solutions are required to process data files of up to 12 million people with high complexity when there are many faces with similar characteristics. "Such a large search space and many difficult cases will require a lot of processing time. However, the assessment limits the processing time of an input image to only 1.5 seconds, which is a significant pressure for the team," said Mr. Pham Dac Quyen, AI engineer, Artificial Intelligence Platform, Viettel AI. Thanks to continuous research and testing of technology, combined with practical experience in the product development process, Viettel AI engineers have gradually solved problems to come up with the most complete final technology.

Explaining the impressive results in the world's top 10 in 5 out of 8 categories, reaching the world's top 4 and Vietnam's top 1 in the 90-degree Mugshot Profile category, a representative of the research team at Viettel AI shared: "Viettel AI aims to build a general method that can recognize faces in many conditions, instead of focusing on finding solutions to solve only 1-2 specialized problems". Engineers have reviewed all steps in the face recognition cycle, identifying the step that has the greatest impact on the final efficiency to focus on optimization, instead of spending a lot of time trying to improve each step in the cycle. By focusing on developing technology comprehensively, allowing face recognition in many non-ideal conditions, Viettel AI has handled the problems of searching and recognizing large numbers of faces, taking less than 1.5 seconds to find a face in a data file of tens of millions of people. Vietnamese people master technology and reach the world Face search and recognition technology is applied in Viettel AI products and services such as Viettel eKYC - an electronic authentication and identification service that allows users to register and use services directly in the digital environment without having to go to transaction points. This technology has high accuracy and security, especially in the banking and finance sector. Thanks to its ability to recognize faces well in many conditions, Viettel eKYC has supported the task of authentication and face comparison to serve hundreds of thousands of new account registrations each month and eliminate cases of face forgery for illegal purposes. The evaluation results of NIST and the application potential of the technology are an affirmation that Vietnamese people can completely master leading AI technologies and compete with major technology companies around the world. In the future, facial recognition and search technology will be able to support population management for provinces and cities such as tracing criminals, detecting suspects or managing immigration.

Facial recognition technology supports access management and population management in the city.

"Viettel AI's technology is recognized as meeting international standards, ranking with leading international units, which will be a great motivation for us to constantly update technology, conquer higher rankings and expand the potential for practical applications," said a representative of the research team. Not only facial recognition technology, Viettel AI is constantly developing and mastering other core AI technologies, aiming to build products that meet international standards, perfecting the AI ​​product and service ecosystem to promote comprehensive digital transformation for the Government and businesses. Not only limited to the territory of Vietnam, Viettel AI aims to export Vietnamese AI products and services abroad, marking Vietnamese AI on the world map.
