This small test set consists of 30 images and one JSON file. The images are a few notebook pages from Rainer Maria Rilke, from the Deutsche Literaturarchiv Marbach (DLA), A:Rilke-Archiv Gernsbach. The JSON file was computationally generated using several AI models and contains information automatically extracted from the images about various visual properties of text, such as word location, colour, orientation, and writing implement. The structure of the JSON file is as follows:

Root (object) ├─ info (object) │   ├─ description   : string │   ├─ contributor   : string │   ├─ version       : string │   ├─ year          : integer │   └─ date_created  : string    # "YYYY-MM-DD" │ ├─ images (array of object) │   └─ [image] (object) │       ├─ id        : integer │       ├─ file_name : string │       ├─ width     : integer │       └─ height    : integer │ └─ annotations (array of object)     └─ [annotation] (object)         ├─ id            : integer         ├─ image_id      : integer         ├─ category_id   : integer         ├─ bbox          : array of 4 numbers      # [x, y, width, height]         ├─ area          : number                 # float         ├─ segmentation  : array of array of number  # [[x1, y1, x2, y2, …]]         ├─ iscrowd       : integer                # 0 or 1         ├─ score         : number                 # float         ├─ color_name    : string         ├─ color_code    : string                 # e.g. "145-144-122"         ├─ orientation   : string                 # e.g. "hor" or "ver"         └─ writing_tool  : string                 # e.g. "pcl"
