Processing / p5.js Tutorial: What is lerp? (Linear Interpolation)

TL;DR

The video explains how the lerp function, short for linear interpolation, can be used to ease or smooth out values in computer vision and sensor readings.

Transcript

hello in this video I'm going to look at the lurp function the lurp function in processing and p5js I'll do it in both environments what is the lurp function by the way lurp is kind of a weird word it stands for linear interpolation which might make you want to stop watching this video immediately now that I said linear interpolation but but stay h...

Questions & Answers

Q: What does the term "lerp" stand for?

"Lerp" stands for linear interpolation, which is a mathematical method used to find a value between two known values.

Q: How can the lerp function be used in computer vision tracking?

When tracking a moving object, the lerp function can be utilized to create a smooth transition between the current position and the target position, eliminating sudden jumps.

Q: How can the lerp function be used to reduce noise in sensor readings?

By applying the lerp function to sensor readings, you can interpolate between noisy values and obtain a smoother output, reducing the impact of noise on the final result.

Q: Can the lerp function be used in both Processing and p5.js?

Yes, the lerp function exists in both environments, with minor syntax differences due to the different programming languages used (Java for Processing and JavaScript for p5.js).

Summary & Key Takeaways

• The lerp function is used to interpolate between two values based on a percentage input.

• It can be used to smoothly transition values, eliminating teleportation-like jumps.

• The function can be applied to computer vision tracking and sensor readings to reduce noise and create smoother output.
