Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider an image represented as a 3x3 matrix. Apply a given kernel for blurring to this image. What is the output image?

💡 Hint: Use the blurring kernel averaging approach.

Challenge 2 Hard

Design a custom kernel for enhancing an image's contrast and explain how it acts differently from a standard sharpening kernel.

💡 Hint: Consider values that emphasize pixel differences.
