Outline Emulating Color-blindness –Approach and Results Correcting Color-blindness –Approaches and Results

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

Emulating Color-blindness: Approach

Emulating Color-blindness: Results Original Protanopic DeuteranopicTritanopic 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 Emulating Color-blindness: Results Original Protanopic DeuteranopicTritanopic

Approach #1: Discrete Histogram Equalization With Rotations: Results

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

1.Detect edges based on color weaknesses 2.Transform edges so that Guarantee all edges are discernable For example: translate red edges to blue and green edges Approach #2: Edge Detection With Directional Filtering: Approach [ ] √ √2 1 0
