Challenge Problems
Push your limits with challenges.
Question 1
Given a 4x4 grayscale image matrix: [[10, 20, 30, 40], [10, 20, 30, 40], [50, 60, 70, 80], [90, 100, 110, 120], apply a basic edge detection filter to it and explain the output.
💡 Hint: Remember how to position the filter over the image and perform the calculations!
Question 2
Create a RGB matrix for an image with three color components (for a small 2x2 pixel image: Red: [[255, 0], [0, 255]], Green: [[0, 255], [255, 0]], Blue: [[0, 0], [255, 255]]). Explain the significance of combining these matrices.
💡 Hint: Think about how mixing paint colors works to create new colors.
