Which blurring technique is effective for reducing general noise?

• Gaussian Blur
• Median Blur
• Bilateral Blur
• All of the above

Which blurring technique is most effective at preserving edges in an image?

• Gaussian Blur
• Median Blur
• Bilateral Blur
• Average Blur

In Median Blur, the pixel value of the center pixel is replaced by:

• The average value of all pixels in the kernel
• The maximum value in the kernel
• The median value of all pixels in the kernel
• The minimum value in the kernel

Which of the following statements is true regarding Gaussian Blur?

• It is also known as Box Blur.
• It performs blurring using the median value.
• It uses a weighted average of neighboring pixels.
• It is not suitable for reducing Gaussian noise.

What is the purpose of the cvtColor function in OpenCV?

• To create a track bar
• To convert an image from one color space to another
• To apply Gaussian blur
• To draw shapes on an image

Which of the following is a valid color space conversion code for cvtColor?

• cv2.COLOR_RGB2HSV
• cv2.COLOR_BGR2XYZ
• cv2.COLOR_BGR2RED
• cv2.COLOR_GRAY2RGB
