Primary Institution: Universidad de Castilla-La Mancha
Hypothesis
Different colour models (RGB, HSI, CIEL*a*b*) will yield varying effectiveness in detecting and classifying regions of interest in microscopic images.
Conclusion
The CIEDE2000 distance for the CIEL*a*b* model reproduces the original colour better than the other models.
Supporting Evidence
- The CIEDE2000 distance model showed higher specificity in distinguishing regions of interest.
- The computational cost of the CIEL*a*b* model is higher than RGB and HSI models.
- ROC analysis indicated that the CIEDE2000 model had lower false positive rates.
Takeaway
This study looks at how different ways of showing colors in images can help scientists find important parts of the pictures better.
Methodology
The study analyzed three colour models (RGB, HSI, CIEL*a*b*) and their effectiveness in processing histological images using various distance formulas.
Limitations
The study may not cover all possible colour models and their applications in different types of tissues.
