Summary:

Images are a powerful, efficient means for communicating information. This book looks at metrics and methods for predicting image quality based on human visual and cognitive information-processing capabilities.

Contents:

1. Introduction

2. Approaches to image quality: 2.1. Statistical measures; 2.2. Measures using visual front-end models; 2.3. Measures incorporating modulation transfer functions; 2.4. Multidimensional impairment measures; 2.5. Task performance measures; 2.6. Measures for color reproduction quality; 2.7. The approach presented in this book

3. Image quality semantics: 3.1. Introduction; 3.2. Quality and information processing; 3.3. Image quality semantics; 3.4. Experiments

4. Visual metrics: discriminative power through flexibility: 4.1. Introduction; 4.2. The usefulness of flexibility; 4.3. Recipe for an optimal metric; 4.4. Vision and visual memory; 4.5. Conclusions; Appendix 4A. Appendix: probability of a topological error

5. Predicting the usefulness and naturalness of color reproductions: 5.1. Introduction; 5.2. Metrics for brightness and color; 5.3. Predicting usefulness; 5.4. Predicting naturalness; 5.5. Conclusions

6. Image quality revisited: 6.1. Introduction; 6.2. What is image quality? 6.3. The internal qualification of attributes; 6.4. An optical metric for overall discriminability; 6.5. An optical metric for overall identifiability; 6.6. Estimating the number of discriminable and identifiable items; 6.7. Partial flexibility; 6.8. Application: black-and-white images of natural scenes; 6.9. Conclusions
