What does "Non-linear Transformation" mean?

Table of Contents

Non-linear transformation is a method used to change data in a way that is not straight or simple. Instead of taking data and just adjusting it up or down, non-linear transformation can twist and turn the data to show different patterns or details.

This technique is useful in many areas, especially in processing images or 3D models. For example, when representing images in a 3D space, non-linear transformations help to compress the data so it takes up less memory while still keeping important information. This makes it easier to handle and share detailed visuals.

In simpler terms, think of non-linear transformation as a way to reshape your data, enabling richer and more complex representations without losing the essence of what the data shows.
