1. What does RGB stand for in color representation?

A) Red, Green, Blue B) Really Good Brightness C) Rapid Graphics Buffer D) Red, Gray, Black

2. What is the main advantage of using HSV color space over RGB for color detection?

A) It uses less memory B) It separates color information from brightness, making it more robust to lighting changes C) It processes faster than RGB D) It only works with ESP32 cameras

3. What 16-bit color format does the ESP32-S3 camera use?

A) RGB888 B) RGB565 C) HSV360 D) BGR555

4. In computer vision, what is a "color blob"?

A) A programming error in color detection B) A connected region of pixels that share similar color properties C) A type of camera lens filter D) A color calibration tool

5. What is the purpose of calculating the centroid of a color blob?

A) To change the blob's color B) To find the center point of the detected object for tracking C) To delete the blob from memory D) To convert RGB to HSV

6. Which factor most affects the accuracy of color detection in robotics?

A) The robot's speed B) Lighting conditions and shadows C) The robot's battery level D) The size of the microSD card

7. In a color-following robot, if the target object appears on the right side of the camera view, what should the robot do?

A) Move forward B) Turn left C) Turn right D) Move backward

8. How can color recognition be applied to traffic light detection?

A) By detecting the shape of the traffic light only B) By identifying red, yellow, and green color regions and their positions C) By measuring the brightness of the light D) By counting the number of lights

9. Design a color sorting system for a factory. Describe how you would use color recognition to sort red, blue, and green objects into separate bins. Include the key components and the decision-making process. (Short Answer)

10. What challenges might you face when implementing color recognition in outdoor environments, and how would you solve them? Provide at least two challenges and their solutions. (Short Answer)
