arcfelismerési

Arcfelismerési, often translated as facial recognition, is a biometric technology capable of identifying or verifying a person from a digital image or a video frame. It compares selected facial features from the image to faces within a database. This technology works by mapping distinctive facial characteristics, such as the distance between the eyes, the shape of the cheekbones, and the contour of the jawline. These measurements are then converted into a numerical code, often called a faceprint.

The process typically involves several steps. First, a face is detected within an image. Then, the facial features are analyzed and converted into a faceprint. Finally, this faceprint is compared to a database of known faceprints to find a match. Arcfelismerési systems can be used for various purposes, including security, access control, and even in social media applications for tagging individuals. However, concerns exist regarding privacy, potential for misuse, and accuracy across different demographics. Research and development continue to improve the algorithms and reduce biases in these systems.
