Computer Vision

A field within Artificial Intelligence (AI) dedicated to empowering machines with the ability to “see” and comprehend the visual world. It focuses on extracting meaningful information from digital images and videos, allowing computers to interpret and analyze visual data much like human vision.

Core Tasks in Computer Vision:

  • Image Recognition: The ability to identify and classify objects, people, or scenes within an image. Imagine a system that can recognize a cat in a picture or differentiate a car from a bicycle.
  • Object Detection: Locating and pinpointing the presence and position of specific objects within an image or video. This goes beyond just identifying the object, but also specifying its location within the frame.
  • Image Segmentation: Partitioning an image into distinct regions or segments, corresponding to different objects or parts of objects. This helps isolate specific features for further analysis.
  • Motion Analysis: Understanding and tracking the movement of objects within a sequence of images or video. This can be used for tasks like traffic monitoring or security surveillance.
  • Scene Reconstruction: Creating a 3D model of a scene from multiple images or videos. This allows for a more comprehensive understanding of the spatial relationships between objects in the environment.

Applications of Computer Vision:

Computer vision has a wide range of applications across various domains, impacting our daily lives:

  • Self-driving Cars: Identifying objects like pedestrians, traffic signals, and other vehicles is crucial for autonomous navigation.
  • Medical Diagnosis: Analyzing medical images (X-rays, MRIs) to detect abnormalities or support diagnoses in healthcare.
  • Facial Recognition: Unlocking smartphones, security systems, or identifying individuals in photographs/videos.
  • Robotics: Enabling robots to interact with their environment by perceiving objects and navigating obstacles.
  • Augmented Reality (AR): Overlaying digital information onto the real world as seen through a camera lens, enhancing our perception.
