Resize

class augmax.Resize(width: int, height: int | None = None)

Crop

class augmax.Crop(x0, y0, w, h)

Crop the image at the specified x0 and y0 with given width and height

Parameters:

• x0 (float) – x-coordinate of the crop’s top-left corner

• y0 (float) – y-coordinate of the crop’s top-left corner

• w (float) – width of the crop

• h (float) – height of the crop

Augmentation Examples for Crop(0, 0, 100, 100)

CenterCrop

class augmax.CenterCrop(width: int, height: int | None = None)

Extracts a central crop from the image with given width and height.

Parameters:

• w (float) – width of the crop

• h (float) – height of the crop

Augmentation Examples for CenterCrop(100, 100)

RandomCrop

class augmax.RandomCrop(width: int, height: int | None = None)

Extracts a random crop from the image with given width and height.

Parameters:

• w (float) – width of the crop

• h (float) – height of the crop

Augmentation Examples for RandomCrop(100, 100)

RandomSizedCrop

class augmax.RandomSizedCrop(width: int, height: int | None = None, zoom_range: Tuple[float, float] = (0.5, 2.0), prevent_underzoom: bool = True)

Extracts a randomly sized crop from the image and rescales it to the given width and height.

Parameters:

• w (float) – width of the crop

• h (float) – height of the crop

• zoom_range (float, float) – minimum and maximum zoom level for the transformation

• prevent_underzoom (bool) – whether to prevent zooming beyond the image size

Augmentation Examples for RandomSizedCrop(100, 100)

HorizontalFlip

class augmax.HorizontalFlip(p: float = 0.5)

Randomly flips an image horizontally.

Parameters:

p (float) – Probability of applying the transformation

Augmentation Examples for HorizontalFlip(p=1.0)

VerticalFlip

class augmax.VerticalFlip(p: float = 0.5)

Randomly flips an image vertically.

Parameters:

p (float) – Probability of applying the transformation

Augmentation Examples for VerticalFlip(p=1.0)

Rotate90

class augmax.Rotate90

Randomly rotates the image by a multiple of 90 degrees.

Augmentation Examples for Rotate90()

Rotate

class augmax.Rotate(angle_range: Tuple[float, float] | float = (-30, 30), p: float = 1.0)

Rotates the image by a random arbitrary angle.

Parameters:

• angle_range (float, float) – Tuple of (min_angle, max_angle) to sample from. If only a single number is given, angles will be sampled from (-angle_range, angle_range).

• p (float) – Probability of applying the transformation

Augmentation Examples for Rotate(p=1.0)

Warp

class augmax.Warp(strength: int = 5, coarseness: int = 32)

Warp an image (similar to ElasticTransform).

Parameters:

• strength (float) – How strong the transformation is, corresponds to the standard deviation of deformation values.

• coarseness (float) – Size of the initial deformation grid cells. Lower values lead to a more noisy deformation.
