Data Science Prerequisites - Numpy, Matplotlib, and Pandas in Python - SciPy Exercise

What is the primary focus of the edge detection exercise?

• Understanding the theory behind edge detection

• Performing mechanical calculations

• Learning about color images

• Exploring 3D matrices

What are Sobel filters used for in this exercise?

• To blur images

• To increase image brightness

• To enhance color saturation

• To detect edges in images

What is the size of the Sobel filters used in this exercise?

• 5 by 5

• 4 by 4

• 3 by 3

• 2 by 2

What is the first step in using Sobel filters on a grayscale image?

• Performing element-wise addition

• Defining the filters

• Combining GX and GY

• Taking the square root

How are the results GX and GY combined in the final step?

• By adding them directly

• By subtracting them

• By multiplying them

• By squaring, adding, and taking the square root
