Quickstart

Import the library:

using DataAugmentation  # Image, CenterResizeCrop, apply, showitem
using TestImages: testimage

Load your data:

image = testimage("lighthouse")

Create an item that contains the data you want to augment:

item = Image(image)

Image{2, ColorTypes.RGB{FixedPointNumbers.N0f8}}() with bounds Bounds(1:512×1:768)

Create a transform:

tfm = CenterResizeCrop((128, 128))

Sequence{Tuple{DataAugmentation.CroppedProjectiveTransform{ScaleKeepAspect{2}, Tuple{Crop{2, DataAugmentation.FromCenter}}}, PinOrigin}}((DataAugmentation.CroppedProjectiveTransform{ScaleKeepAspect{2}, Tuple{Crop{2, DataAugmentation.FromCenter}}}(ScaleKeepAspect{2}((128, 128)), (Crop{2, DataAugmentation.FromCenter}((128, 128), DataAugmentation.FromCenter()),)), PinOrigin()))

Apply the transformation and unwrap the data:

titem = apply(tfm, item)
timage = itemdata(titem)
