Sprite-Data

Repository for all data pertaining to GAN project

Basic Processing

Current workflow for the data collection system is to provide a sprite-sheet, then apply process.py to generate a set of individual sprite images

process.py will perform the following steps

1. extract sprites from sprite-sheet. Currently this relies on a fixed-grid without separation pixels
2. normalize image to RGBA. Also will crop by center or pad with zero.
3. sort images by shape. Note that a single sprite-sheet will add to a single folder. Reason this is useful is that it can automatically, place the different sprite shapes into appropriate bins between sprite-sheets.

Other Processing Activities

Individual scripts can be run to get the specific feature needed. (For example if only interested in normalizing sprites)

Use for GAN

Provided in packaged directory is the compressed dataset generated from finalized directory. Download these files or clone the repository for use in training the GAN.

Alternatively, the project website provides links to cached versions of the dataset. This version may not be up to date.

Classifier Neural Net

TODO

Todo Checklist

• collect more data and further classify the data currently available.
• develop a recursive normalize that copies the directory structure.
• using the manually separated data, train a classifier for easier processing of new data.
