  1. Providing A Natural Solution to Color-Blindness Tudor Dumitras Girish Varatkar Nick Zamora May 09, 2002

  2. Outline • Emulating Color-blindness • Approach and Results • Correcting Color-blindness • Approaches and Results

  3. Emulating Color-blindness: Approach confusion point The Color-blind cannot distinguish colors which lie on the same lines radiating from confusion point

  4. Emulating Color-blindness: Approach

  5. 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

  6. Emulating Color-blindness: ResultsOriginal Protanopic Deuteranopic Tritanopic A person with normal color vision will see a 5, and a person with red/green Color-blindness will see a 2

  7. Emulating Color-blindness: ResultsOriginal Protanopic Deuteranopic Tritanopic Above: www.vischeck.com results Below: Our results

  8. Outline • Emulating Color-blindness • Approach and Results • Correcting Color-blindness • Approaches and Results

  9. Approach #1: Discrete Histogram Equalization With Rotations: Results

  10. Approach #1: Discrete Histogram Equalization With Rotations: Results Original Protanopic Deuteranopic Tritanopic

  11. 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 [ ] 0 -1 -√2 1 0 -1 √2 1 0

  12. Approach #2: Edge Detection With Directional Filtering: Results Original Protanopic Deuteranopic Tritanopic

  13. Approach #3: Fractional V-Distortion: Approach background hidden pattern

  14. Approach #3: Fractional V-Distortion: Results Originals Protanopic Deuteranopic

  15. Approach #3: Fractional V-Distortion: Results Emulation Approach #3 Emulation
