Study Notes
Introduction to Digital Image Processing
- Computer imaging is defined as the acquisition and processing of visual information by computer.
- The ultimate receiver of information can be either a computer or the human visual system.
Computer Vision and Image Processing
- Computer vision involves processing output images for use by a computer.
- Image processing involves processing output images for human consumption.
- Computer vision includes image analysis, which involves:
- Feature extraction: acquiring higher-level image information.
- Pattern classification: identifying objects within the image using higher-level information.
Digital Image
- A digital image can be defined as a 2D function, f(x, y), where x and y are spatial coordinates.
- The amplitude of f at any pair of coordinates (x, y) is called the intensity or gray level of the image at that point.
- A digital image is composed of a finite number of elements, called pixels, each with a particular location and value.
- Common image formats include:
- 1 sample per point (B&W or Grayscale).
- 3 samples per point (Red, Green, and Blue) RGB Coloring System.
Digital Image Processing
- Digital image processing refers to the manipulation and analysis of digital images using various algorithms and techniques to improve quality, extract information, and derive meaningful insights.
- It involves the application of mathematical and computational methods to process images from different sources.
- The primary goal of digital image processing is to enhance, analyze, interpret, and visualize digital images for various applications.
- Digital image processing focuses on two major tasks:
- Improving pictorial information for human interpretation.
- Processing image data for storage, transmission, and representation for autonomous machine perception.
Key Stages/Components of Digital Image Processing
- The continuum from image processing to computer vision can be broken up into low-level, mid-level, and high-level processes.
- The key stages/components of an image processing system are:
- Image acquisition.
- Image processing.
- Image analysis.
- Image understanding.
