Emulating Color-blindness: Approach

confusion point

The Color-blind cannot distinguish colors which lie on the same lines radiating from confusion point

Emulating Color-blindness: ResultsOriginal Protanopic Deuteranopic Tritanopic

Red-Green Color-blind person will see only spots in test above

and should be able to see 56 in the test below

A person with normal color vision will see a 5, and a person with red/green Color-blindness will see a 2

Outline
  • Emulating Color-blindness
    • Approach and Results
  • Correcting Color-blindness
    • Approaches and Results
approach 1 discrete histogram equalization with rotations results10
Approach #1: Discrete Histogram Equalization With Rotations: Results

Original Protanopic Deuteranopic Tritanopic

slide11
Approach #2: Edge Detection With Directional Filtering: Approach
  • Detect edges based on color weaknesses
  • Transform edges so that
    • Guarantee all edges are discernable
    • For example: translate red edges to blue and green edges
