1. Which explanation matches compare histograms without losing location?A. Histograms summarize distributions independently of pixel position.B. Local mappings use neighborhoods, often with a limit on contrast amplification.C. RGB and BGR are channel orders, not different light measurements.D. White balance compensates for the illuminant using channel gains or a reference neutral.

2. Which explanation matches local contrast and noise amplification?A. Histograms summarize distributions independently of pixel position.B. RGB and BGR are channel orders, not different light measurements.C. White balance compensates for the illuminant using channel gains or a reference neutral.D. Local mappings use neighborhoods, often with a limit on contrast amplification.

3. Which explanation matches convert rgb without swapping channels?A. Histograms summarize distributions independently of pixel position.B. Local mappings use neighborhoods, often with a limit on contrast amplification.C. RGB and BGR are channel orders, not different light measurements.D. White balance compensates for the illuminant using channel gains or a reference neutral.

4. For local contrast and noise amplification, which result or action fits this practical case: A local contrast tool reveals a pale vein and a lot of grain.A. Inspect matching histograms beside spatial maps before claiming the leaves look alike.B. Compare the leaf's quiet background before and after a local contrast setting.C. Test a known red patch before a batch conversion and verify the output channel order.D. Compare a gray card under both lights and adjust each image from its own reference.

5. For white balance under changing light, which result or action fits this practical case: The same leaf looks warmer at sunset than at noon.A. Compare a gray card under both lights and adjust each image from its own reference.B. Inspect matching histograms beside spatial maps before claiming the leaves look alike.C. Compare the leaf's quiet background before and after a local contrast setting.D. Test a known red patch before a batch conversion and verify the output channel order.
