Question 10 Multiple Choice (Single Answer)

How does Color Matting differ from抠图?

  1. Color Matting considers color information, while抠图relies solely on luminance.
  2. Color Matting is more suitable for complex backgrounds, while抠图is better for simple backgrounds.
  3. Color Matting produces a grayscale alpha matte, while抠图generates a binary alpha matte.
  4. Color Matting is a more recent technique, while抠图has been used for decades.
