17. Histogram Equalization vs Histogram Matching | Key Differences Explained | Image Processing & CV

Computer Vision Lectures (Topic Wise) Complete Playlist Link -    • Computer Vision Basic Fundamentals  


In this video, we present a clear and in-depth comparison between Histogram Equalization and Histogram Matching, two widely used histogram-based image enhancement techniques in Digital Image Processing (DIP) and Computer Vision (CV).

Understanding the differences between these techniques is crucial for exam preparation, algorithm design, and real-world image enhancement applications, especially in areas such as medical imaging, remote sensing, and AI-based vision systems.

🔍 Topics Covered in This Video:

Brief review of image histograms, PMF, and CDF

What is Histogram Equalization?

What is Histogram Matching (Histogram Specification)?

Key differences in objective, approach, and output

Role of CDF in both equalization and matching

Comparison of contrast enhancement behavior
