Emulating Color-blindness: Approach

confusion point

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

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

and should be able to see 56 in the test below

  • Emulating Color-blindness

    • Approach and Results

  • Correcting Color-blindness

    • Approaches and Results



Approach 1 discrete histogram equalization with rotations results10 l.jpg
Approach #1: Discrete Histogram Equalization With Rotations: Results

Original Protanopic Deuteranopic Tritanopic


Slide11 l.jpg

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
