Ua MM,T5)D E# Mc6eZdZdZ ddZdZdZdZdZy) UnnormalizedBatcha Class for batches of unnormalized data before and after augmentation. Parameters ---------- images : None or (N,H,W,C) ndarray or (N,H,W) ndarray or iterable of (H,W,C) ndarray or iterable of (H,W) ndarray The images to augment. heatmaps : None or (N,H,W,C) ndarray or imgaug.augmentables.heatmaps.HeatmapsOnImage or iterable of (H,W,C) ndarray or iterable of imgaug.augmentables.heatmaps.HeatmapsOnImage The heatmaps to augment. If anything else than ``HeatmapsOnImage``, then the number of heatmaps must match the number of images provided via parameter `images`. The number is contained either in ``N`` or the first iterable's size. segmentation_maps : None or (N,H,W) ndarray or imgaug.augmentables.segmaps.SegmentationMapsOnImage or iterable of (H,W) ndarray or iterable of imgaug.augmentables.segmaps.SegmentationMapsOnImage The segmentation maps to augment. If anything else than ``SegmentationMapsOnImage``, then the number of segmaps must match the number of images provided via parameter `images`. The number is contained either in ``N`` or the first iterable's size. keypoints : None or list of (N,K,2) ndarray or tuple of number or imgaug.augmentables.kps.Keypoint or iterable of (K,2) ndarray or iterable of tuple of number or iterable of imgaug.augmentables.kps.Keypoint or iterable of imgaug.augmentables.kps.KeypointOnImage or iterable of iterable of tuple of number or iterable of iterable of imgaug.augmentables.kps.Keypoint The keypoints to augment. If a tuple (or iterable(s) of tuple), then iterpreted as (x,y) coordinates and must hence contain two numbers. A single tuple represents a single coordinate on one image, an iterable of tuples the coordinates on one image and an iterable of iterable of tuples the coordinates on several images. Analogous if ``Keypoint`` objects are used instead of tuples. If an ndarray, then ``N`` denotes the number of images and ``K`` the number of keypoints on each image. If anything else than ``KeypointsOnImage`` is provided, then the number of keypoint groups must match the number of images provided via parameter `images`. The number is contained e.g. in ``N`` or in case of "iterable of iterable of tuples" in the first iterable's size. bounding_boxes : None or (N,B,4) ndarray or tuple of number or imgaug.augmentables.bbs.BoundingBox or imgaug.augmentables.bbs.BoundingBoxesOnImage or iterable of (B,4) ndarray or iterable of tuple of number or iterable of imgaug.augmentables.bbs.BoundingBox or iterable of imgaug.augmentables.bbs.BoundingBoxesOnImage or iterable of iterable of tuple of number or iterable of iterable imgaug.augmentables.bbs.BoundingBox The bounding boxes to augment. This is analogous to the `keypoints` parameter. However, each tuple -- and also the last index in case of arrays -- has size 4, denoting the bounding box coordinates ``x1``, ``y1``, ``x2`` and ``y2``. polygons : None or (N,#polys,#points,2) ndarray or imgaug.augmentables.polys.Polygon or imgaug.augmentables.polys.PolygonsOnImage or iterable of (#polys,#points,2) ndarray or iterable of tuple of number or iterable of imgaug.augmentables.kps.Keypoint or iterable of imgaug.augmentables.polys.Polygon or iterable of imgaug.augmentables.polys.PolygonsOnImage or iterable of iterable of (#points,2) ndarray or iterable of iterable of tuple of number or iterable of iterable of imgaug.augmentables.kps.Keypoint or iterable of iterable of imgaug.augmentables.polys.Polygon or iterable of iterable of iterable of tuple of number or iterable of iterable of iterable of tuple of imgaug.augmentables.kps.Keypoint The polygons to augment. This is similar to the `keypoints` parameter. However, each polygon may be made up of several ``(x,y)`` coordinates (three or more are required for valid polygons). The following datatypes will be interpreted as a single polygon on a single image: * ``imgaug.augmentables.polys.Polygon`` * ``iterable of tuple of number`` * ``iterable of imgaug.augmentables.kps.Keypoint`` The following datatypes will be interpreted as multiple polygons on a single image: * ``imgaug.augmentables.polys.PolygonsOnImage`` * ``iterable of imgaug.augmentables.polys.Polygon`` * ``iterable of iterable of tuple of number`` * ``iterable of iterable of imgaug.augmentables.kps.Keypoint`` * ``iterable of iterable of imgaug.augmentables.polys.Polygon`` The following datatypes will be interpreted as multiple polygons on multiple images: * ``(N,#polys,#points,2) ndarray`` * ``iterable of (#polys,#points,2) ndarray`` * ``iterable of iterable of (#points,2) ndarray`` * ``iterable of iterable of iterable of tuple of number`` * ``iterable of iterable of iterable of tuple of imgaug.augmentables.kps.Keypoint`` line_strings : None or (N,#lines,#points,2) ndarray or imgaug.augmentables.lines.LineString or imgaug.augmentables.lines.LineStringOnImage or iterable of (#lines,#points,2) ndarray or iterable of tuple of number or iterable of imgaug.augmentables.kps.Keypoint or iterable of imgaug.augmentables.lines.LineString or iterable of imgaug.augmentables.lines.LineStringOnImage or iterable of iterable of (#points,2) ndarray or iterable of iterable of tuple of number or iterable of iterable of imgaug.augmentables.kps.Keypoint or iterable of iterable of imgaug.augmentables.polys.LineString or iterable of iterable of iterable of tuple of number or iterable of iterable of iterable of tuple of imgaug.augmentables.kps.Keypoint The line strings to augment. See `polygons` for more details as polygons follow a similar structure to line strings. data Additional data that is saved in the batch and may be read out after augmentation. This could e.g. contain filepaths to each image in `images`. As this object is usually used for background augmentation with multiple processes, the augmented Batch objects might not be returned in the original order, making this information useful.
