Study Notes

Preface

The book was inspired by a course called "Computer Vision for Computer Graphics".
The book aims to bridge the gap between computer vision techniques and their applications in computer graphics.
The author has over 40 years of experience conducting computer vision research in corporate research labs.
The focus is on techniques that have practical real-world applications and work well in practice.
The book emphasizes basic techniques that work under real-world conditions.
It is suitable for undergraduate and graduate courses in computer vision.
The book includes exercises at the end of each chapter for practical implementation.
The author encourages students to use their own personal photographs for their projects.
The book utilizes four high-level approaches to computer vision problem solving:
- Scientific: build detailed models of the image formation process and develop mathematical techniques to invert them.
- Statistical: use probabilistic models to quantify the prior likelihood of unknowns and noisy measurement processes.
- Engineering: develop simple and efficient techniques that work well in practice.
- Data-driven: collect representative data to tune or learn model parameters and validate performance.
The book emphasizes algorithmic solutions and robust techniques for real-world scenarios.
Algorithms presented are high-level and require further details to be filled in by students.
