Questions

Question 1 Multiple Choice (Single Answer)

What is the purpose of trimap matting?

  1. To extract the foreground and background of an image.
  2. To create a mask for an image.
  3. To generate a depth map for an image.
  4. To remove noise from an image.
Question 2 Multiple Choice (Single Answer)

What is the difference between trimap matting and alpha matting?

  1. Trimap matting uses a trimap to label the pixels, while alpha matting uses an alpha channel.
  2. Trimap matting is more accurate than alpha matting.
  3. Trimap matting is less computationally expensive than alpha matting.
  4. Trimap matting can be used to extract the foreground and background of an image, while alpha matting can only be used to create a mask.
