Challenge Problems
Push your limits with advanced challenges
Given a series of images, design a Python program using OpenCV that converts each to grayscale, resizes to 150x150, and applies a Gaussian blur. Discuss potential challenges.
💡 Hint: Start with one function at a time and build your program incrementally.
Using OpenCV, how would you create a composite image from three images using blurring and drawing? Design algorithms and provide a sample code.
💡 Hint: Layering images can often mislead. Keep track of boundaries and structure initially.
