Challenge Problems
Push your limits with challenges.
Question 1
Given a 5x5 image matrix, apply an edge detection filter and calculate the resulting feature map. Use the following image matrix: [100, 150, 100, 150, 100], [150, 200, 150, 200, 150], [100, 150, 100, 150, 100], [150, 200, 150, 200, 150], [100, 150, 100, 150, 100]
💡 Hint: Remember to carefully apply the convolution operation step by step to get accurate results.
Question 2
Discuss how edge detection can fail in case of noisy images. What preprocessing techniques can you adopt to improve results before applying edge detection?
💡 Hint: Consider what occurs when you add noise to a clear image.
