Question 1.
What function is used to blur an image in OpenCV?
Show hintHide hint
Think of the name that involves a curve.
Question 2.
What is meant by kernel size in the GaussianBlur function?
Show hintHide hint
It's like the size of a window for blurring.
3Question 3.
What is the main purpose of using Gaussian blur?
- To sharpen images
- To reduce noise
- To enhance colors
Show hintHide hint
Think about the effects of blurring on an image.
4Question 4.
True or False: A larger kernel in GaussianBlur means more detail is retained.
- True
- False
Show hintHide hint
Consider the relationship between kernel size and detail.
Question 5.
You want to blur an image using GaussianBlur. Written in code, how would you implement this for an image named 'photo.jpg' with a kernel size of (7, 7)?
Show hintHide hint
Remember to load the image first before applying the blur.
Question 6.
Describe how changing both the kernel size and sigmaX in the GaussianBlur function affects the resulting image. Provide an example.
Show hintHide hint
Think about the relationships between kernel size and pixel averaging.
