Image Processing

Image processing is a fundamental domain of computer science and digital signal processing that focuses on the manipulation and analysis of digital images. It serves as a crucial bridge between raw visual data and higher-level computer vision applications.

Core Concepts

Digital Image Representation

• Images are represented as discrete matrices of pixels
• Each pixel contains numerical values representing:
  • Intensity (grayscale images)
  • Color components (RGB, CMYK, or other color spaces)
  • Additional channels (alpha transparency, depth)

Basic Operations

1. Point Operations

   • Brightness and contrast adjustment
   • Color correction and balancing
   • Thresholding

2. Neighborhood Operations

   • Image filtering (smoothing, sharpening)
   • Edge detection
   • Noise reduction

3. Geometric Transformations

   • Scaling
   • Rotation
   • Image warping
