Computer Vision helps self-driving cars in:
• Identifying objects: Self-driving cars have cameras and sensors that use Computer Vision to detect objects
around them. This includes other vehicles, pedestrians crossings, traffic signs, traffic lights, and even road
markings. By recognising these objects, the car can make safe decisions, such as stopping at a red light or
avoiding obstacles.
• Navigating routes: Computer Vision helps the car to determine the optimal route by understanding the road
layout and identifying key points, such as intersections, lanes, and turns. It works along with other technologies
like GPS to ensure the car follows the correct route.
• Monitoring the environment: The car constantly monitors its environment using Computer Vision to track
the distance of surrounding vehicles, ensure the road is clear, or detect any changes that, happen in the
surroundings. This allows the car to respond to unexpected situations, such as an animal crossing the road or
sudden changes in weather.
Medical Imaging
For many years, computer-supported medical imaging has been a trusted tool for doctors and medical
professionals. This technology is not just about taking and viewing images, but also about helping doctors
analyse and interpret those images to understand a patient's health better.
Computer Vision helps medical imaging in:
• Creating and analysing images: Medical imaging technologies, like X-rays, CT scans, and MRIs, capture detailed
images of a patient's body. Computer Vision helps doctors examine these images to look for signs of illness or
injury, such as broken bones, tumors, or other medical conditions.
• Converting 2D images to 3D models: One of the most important things Computer Vision can do in medical
imaging is convert flat 2D images (like a traditional X-ray) into interactive 3D models. These 3D models give
doctors a more detailed view of the body, allowing them to see things from different angles. This helps doctors
better understand the situation and make more accurate decisions.
• Helping doctors to interpret results: Computer Vision not only helps in taking images but also in interpreting
them. It can point out areas that need further attention, making it easier for doctors to spot problems that might
be hard to see with the naked eye. This is especially helpful in detecting small changes that might indicate the
beginning of a disease, such as early stages of cancer.
• Assisting in Surgery: Computer Vision is used in some surgeries to guide doctors. It can show real-time images
of the area being operated on, helping the surgeon make more precise cuts and decisions.
Google Translate App
The Google Translate app has a very handy feature that helps you read signs or text in a foreign
language. Instead of manually typing words or phrases to translate, you can simply point your phone’s
camera at the text, and the app will instantly show you the translation in your preferred language.
