Tinker300 dots of pure noise, waiting to develop.
Chapter 2 of 7
Step by step
The pictures come out clean, but each one takes many runs of the denoiser. The team wants to know what fewer would cost.
This chapter: What do you give up when you take fewer steps?
About this chapter
You will learn
- Why each step is one run of the denoiser
- Why fewer steps draw a rougher picture
- Why the step count is a trade of cost against quality
Words you’ll meet
- Step
- One run of the denoiser: it guesses the clean picture and moves a little toward it.
- Roughness
- Here, how far the dots land from the hinge’s outline on average. 0 is a perfect drawing.
- Cost
- Here, how many times the denoiser runs to make one picture.
Step 1 of 3
A toy denoiser trained on the hinge’s outline draws it with 300 dots. Each is one run of the denoiser.
