Pizzaïolo Dataset

Pizzaïolo Dataset This dataset contains 4800 samples of synthetic pizza images generated from and annotated with the Pizzaïolo Ontology. The synthetic pizza images were generated with the Pizzaiolo Python library. If you use Pizzaiolo or the Pizzaïolo Dataset, please cite as : Grégory Bourguin, Arnaud Lewandowski.

The concepts.json file contains a Python dict for concepts encoding : key(s) : a concept id (uint) value(s) : the concept name (string) (i.e. the short name of the concept class in the Pizzaïolo Ontology) Bouding Boxes The bounding boxes represent the localization of the concepts instances constituting a pizza sample. Each img_XXXXX_bboxes.json file contains a Python dict: key(s) : the name (string) of each concept class present in the sample value(s) : list of all the bouding boxes for the corresponding concept key NB: each bounding box is encoded as a Python (sub)list : [ x_left, y_top, width, height ] Contours The contours represent the localization and shape of the concepts instances constituting a pizza sample. Each img_XXXXX_contours.json file contains a Python dict : key(s) : the name (string) of each concept class present in the sample value(s) : a list of all the contours for the corresponding concept key NB: contours are encoded as OpenCV Contours. Semantic Segmentation Each img_XXXXX_segmentation.txt file contains a Python
