Computer Vision refers to the field of study and technology that enables computers to interpret and understand visual information from the world, including images and videos. It aims to replicate the human visual system’s ability to perceive, analyse, and make sense of visual data, empowering machines to extract meaningful insights, detect patterns, and perform tasks traditionally associated with human vision.
A more comprehensive definition of Computer Vision highlights its multidisciplinary nature, drawing upon various techniques from computer science, mathematics, and image processing. It encompasses a range of tasks, including image recognition, object detection, image segmentation, motion analysis, and scene understanding.
Examples of applications
Computer Vision finds application across numerous domains and industries. Here are a few notable examples:
- Autonomous Vehicles: Computer Vision plays a crucial role in enabling autonomous vehicles to perceive and navigate their surroundings. It helps in identifying and tracking objects, detecting traffic signs and signals, and understanding the road environment, ensuring safe and efficient autonomous driving.
- Surveillance and Security: Computer Vision is employed in surveillance systems to monitor and analyse video footage for various security purposes. It can detect and track suspicious activities, identify individuals, and provide real-time alerts in critical situations, enhancing public safety and security.
- Medical Imaging: Computer Vision aids in the analysis of medical images, such as X-rays, MRIs, and CT scans. It can assist in the detection of diseases, tumours, and anomalies, helping healthcare professionals make accurate diagnoses and treatment plans.
- Augmented Reality: Computer Vision forms the foundation of augmented reality (AR) applications. It enables the overlay of digital information and virtual objects onto the real world, enhancing the user’s perception and interaction with their environment.
- Retail and E-commerce: Computer Vision is used in applications like product recognition, visual search, and augmented reality try-on. It allows customers to search for products based on images, try virtual product simulations, and facilitates automated inventory management.
The application of Computer Vision offers several benefits:
