Generalised Hough transform

Generalised Hough Transform is a fancy way of finding things in pictures or images. Imagine you are playing "Find the Hidden Object" with your friends, but instead of searching for objects in real life, you are searching for them in pictures.

The Generalised Hough Transform helps you do just that. It works by looking at different pictures of different objects and remembering key points (like the shape or outline) of each object. When it's time to play "Find the Hidden Object," the Generalised Hough Transform can quickly look at the key points of the object you want to find and compare them to the pictures it remembers.

Once it finds the object in the picture you are searching, it can tell you where it is and how it's oriented (like up or down). So, just like you might read the picture book “Where's Waldo?" and find Waldo in different pictures, the Generalised Hough Transform can do the same thing using pictures of objects in the real world. And that's all there is to it!
