Study Notes
Introduction and Overview
- Humans rely heavily on vision for survival and complex tasks
- Image processing is the science of modifying digital images using a computer
- Image processing applications span various fields (medical, industrial, military, law enforcement, consumer electronics, internet)
Basic Concepts and Terminology
- An image is a visual representation of an object, person, or scene (2D)
- A digital image is a representation of a 2D image using points (pixels)
- Digital image processing is the science of modifying digital images by computer
- Image processing is usually performed automatically via algorithms
- Image interpretation can be low-level (modifications of the original image), mid-level (extracting scene attributes), or high-level (analyzing the scene)
Examples of Typical Image Processing Operations
- Sharpening (Figure 1.1): Enhances edges and details in an image, done in spatial or frequency domains
- Noise Removal (Figure 1.2): Uses filters to reduce noise in an image
- Deblurring (Figure 1.3): Removes blur from images, often due to camera motion or focus issues
- Edge Extraction (Figure 1.4): Identifies and extracts edges to separate objects in an image
- Binarization (Figure 1.5): Reduces the number of gray levels in a grayscale image to two levels (black and white)
- Blurring (Figure 1.6): Reduces image detail and emphasizes shapes, performed using spatial or frequency domains
- Contrast Enhancement (Figure 1.7): Improves image contrast, often using histogram equalization
Components of a Digital Image Processing System
- Components include acquisition, storage, display, and a computer
- This general system can be applied to all image processing tasks
- Digital still cameras function as a practical example of this system (with CCD sensor, flash memory, and display for example)
