Intensity Levels → Contrast
Contrast → Image Quality
Image Quality → Feature Visibility
Feature Visibility → Computer Vision Accuracy
Resolution + Bit Depth → Image Usability
Higher Resolution → Larger Storage Requirement
Higher Bit Depth → Better Visual Representation
Better Image Quality → More Reliable Decision Making
