Artificial Intelligence for Beginners' exciting chapter on computer vision combines the capabilities of AI and visual perception. In order for computers to understand and absorb visual information similarly to how people do, it involves teaching them to "see" and analyze images or movies. This technology, which also constantly extends the boundaries of the possible, has altered both the autonomous vehicle and healthcare industries.

What is computer vision in AI?

Computer vision in AI is fundamentally the capacity of a machine to derive informative data from visual data. It enables machines to emulate human vision by processing, analyzing, and comprehending images and videos. Computer vision systems can identify objects, recognize faces, find patterns, and even comprehend complicated images by using algorithms and deep learning approaches.

 The most important aspects are as follows:

  • Image Recognition: Recognising and categorizing objects, sceneries, and patterns in photographs is known as image recognition.
  • Object Detection and Tracking: Locating & tracking objects in movies for surveillance & autonomous vehicles is known as object detection and tracking.
  • Image segmentation: Breaking up images into smaller pieces in order to recognize objects and regions.
  • Pose Estimation: Pose estimation is the process of figuring out where and how people or objects are positioned.
  • Image generation: the process of producing or changing images utilizing methods like style transfer.
  • Scene Understanding: Understanding a scene's context and significance is known as scene understanding.
  • Video analysis: The process of tracking objects and identifying actions in videos.
  • CNNs and deep learning: Using neural networks to boost performance.
  • Dataset Annotation and Training: Large dataset labeling for algorithm training in the context of dataset annotation.
  • Applications: Used in areas such as facial recognition, medical imaging, and autonomous cars.

How computer vision works

The steps listed below describe how computer vision works:

  • Image acquisition: acquiring images using cameras or other imaging equipment.
  • Preprocessing: Improving the quality of an image using methods like noise removal or image scaling.
  • Feature extraction: Using algorithms in AI, to locate significant traits or patterns in the image.
  • Machine learning: The process of analyzing and categorizing extracted features using learned models.
  • Classification or prediction: Making judgments or forecasts in light of the data analysis.

The History of computer vision in AI

Following is an overview of history of computer vision:

  • Early Uses: Barcode scanning & character recognition were computer vision's first applications.
