imgaug.augmenters.pooling

Augmenters that apply pooling operations to images.

List of augmenters:

class imgaug.augmenters.pooling.AveragePooling(kernel_size=(1, 5), keep_size=True, seed=None, name=None, random_state='deprecated', deterministic='deprecated')[source]

Bases: imgaug.augmenters.pooling._AbstractPoolingBase

Apply average pooling to images.

This augmenter pools images with kernel sizes H x W by averaging the pixel values within these windows. For e.g. 2 x 2 this halves the image size. Optionally, the augmenter will automatically re-upscale the image to the input size (by default this is activated).

Note that this augmenter is very similar to AverageBlur. AverageBlur applies averaging within windows of given kernel size without striding, while AveragePooling applies striding corresponding to the kernel size, with optional upscaling afterwards. The upscaling is configured to create “pixelated”/”blocky” images by default.

Note

During heatmap or segmentation map augmentation, the respective arrays are not changed, only the shapes of the underlying images are updated. This is because imgaug can handle maps/maks that are larger/smaller than their corresponding image.

Supported dtypes:

See avg_pool().

Variables:
  • kernel_size (int or tuple of int or list of int or imgaug.parameters.StochasticParameter or tuple of tuple of int or tuple of list of int or tuple of imgaug.parameters.StochasticParameter, optional) –

    The kernel size of the pooling operation.

    • If an int, then that value will be used for all images for both kernel height and width.
    • If a tuple (a, b), then a value from the discrete range [a..b] will be sampled per image.
    • If a list, then a random value will be sampled from that list per image and used for both kernel height and width.
    • If a StochasticParameter, then a value will be sampled per image from that parameter per image and used for both kernel height and width.
    • If a tuple of tuple of int given as ((a, b), (c, d)), then two values will be sampled independently from the discrete ranges [a..b] and [c..d] per image and used as the kernel height and width.
    • If a tuple of lists of int, then two values will be sampled independently per image, one from the first list and one from the second, and used as the kernel height and width.
    • If a tuple of StochasticParameter, then two values will be sampled indepdently per image, one from the first parameter and one from the second, and used as the kernel height and width.
  • keep_size (bool, optional) – After pooling, the result image will usually have a different height/width compared to the original input image. If this parameter is set to True, then the pooled image will be resized to the input image’s size, i.e. the augmenter’s output shape is always identical to the input shape.
  • seed (None or int or imgaug.random.RNG or numpy.random.Generator or numpy.random.BitGenerator or numpy.random.SeedSequence or numpy.random.RandomState, optional) – See __init__().
  • name (None or str, optional) – See __init__().
  • random_state (None or int or imgaug.random.RNG or numpy.random.Generator or numpy.random.BitGenerator or numpy.random.SeedSequence or numpy.random.RandomState, optional) – Old name for parameter seed. Its usage will not yet cause a deprecation warning, but it is still recommended to use seed now. Outdated since 0.4.0.
  • deterministic (bool, optional) – Deprecated since 0.4.0. See method to_deterministic() for an alternative and for details about what the “deterministic mode” actually does.

Examples
