Questions and Answers

In the context of image processing, what does the function F(x, y) represent?

  • The pixel color at position (x, y)
  • The horizontal dimension of the image
  • The intensity of a value at position (x, y) (correct)
  • The blurring effect at position (x, y)

How is a color image represented as a function?

  • As a matrix-valued function with three separate matrices stacked together
  • As a single-valued function with three separate values stacked together
  • As a vector-valued function with three separate functions stacked together (correct)
  • As a scalar-valued function with three separate values multiplied together

What does the function F(x, y) contain in a color image?

  • A single number representing the light intensity
  • A matrix representing the pixel locations
  • A vector representing the image dimensions
  • Three numbers representing the color intensities (correct)
