Machine vision

Short answer

Machine vision enables machines to acquire and understand images. It helps AI by providing perception for robots, enabling automation, recognition tasks, autonomous vehicles, medical diagnosis, and learning system input.

What is machine vision? How does machine vision help in Artificial Intelligence?

Machine (computer) vision is the field of AI that enables machines to acquire, process, analyse and understand images and video from the real world and to produce symbolic information or decisions from them, much as human vision does.

Stages

 Camera/sensor -> Image acquisition -> Pre-processing (noise removal)
   -> Segmentation (edges, regions) -> Feature extraction
   -> Object recognition -> Interpretation / action
  1. Image acquisition (camera, scanner, sensors).
  2. Pre-processing: noise removal, contrast enhancement.
  3. Segmentation: find edges, regions and objects.
  4. Feature extraction: shape, colour, texture, corners.
  5. Recognition and interpretation: classify objects and understand the scene.

How machine vision helps AI

  • Gives intelligent agents and robots perception of their surroundings (sensing is the first step of an agent's action cycle).
  • Enables automation: inspection of products in factories, sorting, assembly.
  • Supports recognition tasks: face, fingerprint, handwriting (OCR) and number-plate recognition.
  • Enables autonomous vehicles and drones to detect lanes, pedestrians and obstacles.
  • Helps medical diagnosis from X-ray, CT and MRI images, and satellite image analysis.
  • Provides input for learning systems (e.g. neural networks learn from images), and for surveillance and security.
