Which of the following is a common application of computer vision?

• A. Voice recognition software
• B. Face unlock feature on smartphones
• C. Weather forecasting models
• D. Data encryption methods

Answer: (B)

The face unlock feature on smartphones is a prime example of a common application of computer vision. This technology utilizes algorithms to analyze and interpret visual information, particularly in identifying and verifying human faces. When a user attempts to unlock their smartphone, the camera captures the image of the user's face, and the computer vision software processes this image to match it against the stored facial data. If there is a successful match, access is granted, demonstrating the ability of computer vision to recognize and differentiate between different individuals. In contrast, voice recognition software relies on audio processing rather than visual data, while weather forecasting models are built on statistical and environmental data rather than visual perception. Data encryption methods involve securing information using mathematical algorithms and do not pertain to analyzing images or visual data. Therefore, the face unlock feature represents a direct use of computer vision in technology today.
