Introduction




What is digital image processing?




Digital image processing is the manipulation of digital images by computer algorithms. A digital image is a representation of a two-dimensional scene using a finite number of discrete values, called pixels. Each pixel has a numerical value that corresponds to its brightness or color. Digital image processing can be used to enhance, restore, compress, segment, classify, recognize, measure, analyze, synthesize, or transform digital images for various purposes.


Why is it important?




Digital image processing has many important applications in various domains, such as:



  • Medical imaging: Digital image processing can help diagnose diseases, monitor treatments, perform surgeries, and visualize anatomical structures.



  • Remote sensing: Digital image processing can help extract information from satellite or aerial images, such as land cover, vegetation, water resources, weather patterns, etc.



  • Computer vision: Digital image processing can help computers understand and interact with the visual world, such as face recognition, object detection, scene understanding, etc.



  • Biometrics: Digital image processing can help identify or verify individuals based on their physical or behavioral characteristics, such as fingerprints, iris patterns, facial features, etc.



  • Artificial intelligence: Digital image processing can help create intelligent systems that can learn from and generate realistic images, such as deep learning, generative adversarial networks, style transfer, etc.
