1. Computer vision is the ability of computers to interpret and understand visual information from the world around us. Two applications of computer vision are: Self-driving cars, and Google Lens.
2. Computer vision generally works in three basic steps:
Acquiring the image/video from a camera
Processing the image
Understanding the image
3. AI plays a crucial role in computer vision by enabling computers to see and analyse the visual data. AI algorithms provide the computational power needed to analyse large amount of image and video data and extract meaningful information from it.
4. The cameras installed in self-driving cars capture videos from different angles around the car. These videos are fed into computer vision software, which then processes them in real-time, which detects road conditions, like roadblocks, road constructions, speed breaker, etc., reads traffic signs, and detects other cars and objects like pedestrians. The car then moves based on the information generated by the computer vision algorithm, which will avoid hitting obstacles and safely drive passengers to their destination.
5. Two applications of Google Lens are:
Translation: Google Lens is used to translate text to the language of your choice in real-time.
