Simple Calculation
“Split” the color image into the three color “component images” (red, green, blue)
- RGB images appear “black & white” (monochrome)
Want to combine the component images to create a “new” image of just the “original” text beneath the “overwriting”
- Select two images
- Solve 2 equations for 2 unknowns
- Scale one image to “match” the other
- Subtract to create a difference image with only one text
