1. Preface

tools for work on the GANfitti dataset

2. Dataset

2.1 Collection

Berlin, Kassel Spring 2022

2.2 Cropping

create AOI file -> one line per graffitti -> relative coords script creates images from labels use padd_all_images_512.sh -> or equvalent script with changed size 256 1024 etc

2.3 Label Texts

load images webserver (create_text_labels_editor.py) json per image with key value pairs like that:

{
    "text": "darig", 
    "background": "concrete", 
    "fill": "white", 
    "outline": "red, black",

}

2.4 create free text descriptions from jsons

"a graffiti reading 'XXXX' on a 'background', with 'fill' fill-color, 'outline' outline(s), in a 'style' style. with 'highlights'" and variantions thereof, thereby creating a larger dataset

2.3 Possible Options

continue here!

python3 editor.py -i ~/Pictures/GANfitti/raw_graff_data/ -o ~/Pictures/GANfitti/labels`

use yolov5 to test if labeling can already be automated

label texts
