Question 5
Domain 3: Describe Azure AI services for computer vision and document processingWhat does a single layer of pixel values in an image represent?
Correct answer: B
Explanation
A single layer of pixel values represents one intensity channel, which is the definition of a "grayscale image." In grayscale, each pixel stores brightness only, rather than separate red, green, and blue values used in color images.
Why each option is right or wrong
A. RGB color hues
B. Grayscale image
A one-channel image stores only one numeric intensity per pixel, rather than three separate RGB components. In image processing terms, that corresponds to an 8-bit or otherwise single-band luminance map, which is the standard representation of a grayscale image.
C. Object detection
