Ever wondered how the function toUpperCase is implemented in lower level? Would it be possible for you to implement this method yourself without using any libraries?

Template Matching and Color Segmentation in Image Processing: Where's Wally?
Template Matching and Color Segmentation in Image Processing: Where's Wally?

Remember Wally from Martin Handford’s children book series Where’s Wally? When you were a kid, you probably spent plenty of time trying to find Wally in those illustrations. Now as an adult, we can write a simple MATLAB program that can automatically find Wally for us!
