Facial recognition technology utilizes algorithms to analyze and identify individuals based on their facial characteristics. These algorithms extract features like the distance between the eyes, the shape of the jawline, and the prominence of cheekbones to create a unique "facial signature" for each individual. There are two main categories of facial recognition algorithms:

2D recognition

This technology relies on analyzing two-dimensional images or video footage to identify individuals. While effective in controlled environments, 2D recognition can be susceptible to variations in lighting, pose, and facial expressions.

2D recognition technology focuses on analyzing two-dimensional images to identify and classify objects or patterns effectively. Saiwa, with its state-of-the-art image processing and detection and authentication services, harnesses this technology to offer advanced solutions.

Saiwa utilizes similar recognition methods with two face detectors—one prioritizing speed and the other accuracy. Our 2D recognition technology excels in detecting and localizing reference faces across multiple images, even those with unknown subjects. This service is particularly beneficial for applications in authentication, security, social media, and marketing.

Saiwa’s face detection service includes features like enhancing from a fast recognition algorithm, handling multiple reference images per individual, and exporting results to user cloud space or locally. By employing our face detection service, we ensure precise and reliable face recognition, adapted for frontal or near-frontal faces. With our comprehensive 2D recognition technology, Saiwa provides robust solutions for diverse applications, streamlining authentication and enhancing security measures.

3D recognition

This advanced technology utilizes depth sensors to create a three-dimensional model of the face. This allows for more robust recognition, as it is less affected by pose and lighting variations compared to 2D technology.
