# Danbooru SFW 512px Character Crops |
|
This dataset includes image and bounding box pairs where the images are samples from |
|
Danbooru 2021 SFW and the bounding boxes are crops of the central character(s). It can |
|
be used to train a model that automatically crops the base dataset in order to create a cleaner |
|
and more character-centric version. Importantly, the crops aim to remove artifacts such as |
|
horizontal/vertical bars that could negatively impact performance on image generation tasks. |
|
|
|
## Bounding Boxes |
|
The base images are all 512x512, the bounding boxes represent crops with a maximium size of |
|
512x512 and a minimum size of 128x128. Each bounding box is represented as a 3-dimensional |
|
vector [x, y, s] where x is the left coordinate of the box, y is the top coordinate of the box, |
|
and s is the side length of the box. These elements have been converted to floats and |
|
normalized according to their maximum possible values (512). For example, [16, 28, 256] would |
|
have been converted to [16/512, 28/512, 256/512], or [0.03125, 0.0546875, 0.5]. Using this |
|
conversion, the minimum value of s is 128/512, or 0.25. |
