Question1

How is a binary image encoded?

Expected answer

Using only black and white pixels.
Using a full range of colors.
Using grayscale values.
None of the above.

Question2

What is the main difference between grayscale and color images in terms of pixel encoding?

Grayscale images encode each pixel with a single value representing light intensity, whereas color images encode each pixel with multiple values representing different color channels (e.g., RGB).

Question3

Encode the color image pixel with RGB values (125, 200, 50).

The RGB values (125, 200, 50) represent the pixel's red, green, and blue intensities, which combine to display the specific color at that pixel location.
