aeroplane, bicycle, bird, boat, bottle, bus, car, cat, chair, cow, diningtable, dog, horse, motorbike, person, pottedplant, sheep, sofa, train, tvmonitor
and additional 3 classes : head, hand, foot for person.
Parameters
-----------
path : str
The path that the data is downloaded to, defaults is ``data/VOC``.
dataset : str
The VOC dataset version, `2012`, `2007`, `2007test` or `2012test`. We usually train model on `2007+2012` and test it on `2007test`.
contain_classes_in_person : boolean
Whether include head, hand and foot annotation, default is False.
Returns
---------
imgs_file_list : list of str
Full paths of all images.
imgs_semseg_file_list : list of str
Full paths of all maps for semantic segmentation. Note that not all images have this map!
imgs_insseg_file_list : list of str
Full paths of all maps for instance segmentation. Note that not all images have this map!
imgs_ann_file_list : list of str
Full paths of all annotations for bounding box and object class, all images have this annotations.
classes : list of str
Classes in order.
classes_in_person : list of str
Classes in person.
classes_dict : dictionary
Class label to integer.
n_objs_list : list of int
Number of objects in all images in ``imgs_file_list`` in order.
objs_info_list : list of str
Darknet format for the annotation of all images in ``imgs_file_list`` in order. ``[class_id x_centre y_centre width height]`` in ratio format.
objs_info_dicts : dictionary
The annotation of all images in ``imgs_file_list``, ``{imgs_file_list : dictionary for annotation}``,
format from `TensorFlow/Models/object-detection <https://github.com/tensorflow/models/blob/master/object_detection/create_pascal_tf_record.py>`__.
