class imgaug.augmenters.convolutional.Convolve(matrix=None, seed=None, name=None, random_state='deprecated', deterministic='deprecated')[source]

Bases: imgaug.augmenters.meta.Augmenter

Apply a convolution to input images.

    1. rejected by cv2.filter2D().
    1. causes error: cv2.error: OpenCV(3.4.2) (…)/filter.cpp:4487: error: (-213:The function/feature is not implemented) Unsupported combination of source format (=1), and destination format (=1) in function ‘getLinearFilter’.
    1. mapped internally to int16.
    1. mapped internally to float32.
Parameters:

  • matrix (None or (H, W) ndarray or imgaug.parameters.StochasticParameter or callable, optional) –

    The weight matrix of the convolution kernel to apply.

    • If None, the input images will not be changed.
    • If a 2D numpy array, that array will always be used for all images and channels as the kernel.
    • If a callable, that method will be called for each image via parameter(image, C, random_state). The function must either return a list of C matrices (i.e. one per channel) or a 2D numpy array (will be used for all channels) or a 3D HxWxC numpy array. If a list is returned, each entry may be None, which will result in no changes to the respective channel.

  • 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 Outdated since 0.4.0.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.

class imgaug.augmenters.convolutional.DirectedEdgeDetect(alpha=(0.0, 0.75), direction=(0.0, 1.0), seed=None, name=None, random_state='deprecated', deterministic='deprecated')[source]

Bases: imgaug.augmenters.convolutional.Convolve

Detect edges from specified angles and alpha-blend with the input image.

This augmenter first detects edges along a certain angle. Usually, edges are detected in x- or y-direction, while here the edge detection kernel is rotated to match a specified angle. The result of applying the kernel is a black (non-edges) and white (edges) image. That image is alpha-blended with the input image.

Supported dtypes:

See Convolve.

Parameters:

  • alpha (number or tuple of number or list of number or imgaug.parameters.StochasticParameter, optional) – Blending factor of the edge image. At 0.0, only the original image is visible, at 1.0 only the edge image is visible.

    • If a number, exactly that value will always be used.
    • If a tuple (a, b), a random value will be sampled from the interval [a, b] per image.
    • If a list, a random value will be sampled from that list per image.
    • If a StochasticParameter, a value will be sampled from that parameter per image.

  • direction (number or tuple of number or list of number or imgaug.parameters.StochasticParameter, optional) – Angle (in degrees) of edges to pronounce, where 0 represents 0 degrees and 1.0 represents 360 degrees (both clockwise, starting at the top). Default value is (0.0, 1.0), i.e. pick a random angle per image.

    • If a number, exactly that value will always be used.
    • If a tuple (a, b), a random value will be sampled from the interval [a, b] will be sampled per image.
    • If a list, then a random value will be sampled from that list per image.
    • If a StochasticParameter, a value will be sampled from the parameter per image.

  • 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

>>> import imgaug.augmenters as iaa
>>> aug = iaa.DirectedEdgeDetect(alpha=1.0, direction=0)

Turn input images into edge images in which edges are detected from the top side of the image (i.e. the top sides of horizontal edges are part of the edge image, while vertical edges are ignored).

>>> aug = iaa.DirectedEdgeDetect(alpha=1.0, direction=90/360)

Same as before, but edges are detected from the right. Horizontal edges are now ignored.

>>> aug = iaa.DirectedEdgeDetect(alpha=1.0, direction=(0.0, 1.0))

Same as before, but edges are detected from a random angle sampled uniformly from the interval [0deg, 360deg].

>>> aug = iaa.DirectedEdgeDetect(alpha=(0.0, 0.3), direction=0)

Similar to the previous examples, but here the edge image is alpha-blended with the input image. The result is a mixture between the edge image and the input image. The blending factor is randomly sampled between 0% and 30%.

Sharpens input images with a variable lightness sampled uniformly from the interval [0.75, 2.0] and with a fully random blending factor (as in the above example).
