AugMix aims to produce images with variety while preserving the image semantics and local statistics. During the augmentation process, the same augmentation is applied across all images in the batch in num_chains different ways, with each chain consisting of chain_depth augmentations.
Usage
layer_aug_mix(
object,
value_range = c(0L, 255L),
num_chains = 3L,
chain_depth = 3L,
factor = 0.3,
alpha = 1,
all_ops = TRUE,
interpolation = "bilinear",
seed = NULL,
data_format = NULL,
...
)Arguments
- object
Object to compose the layer with. A tensor, array, or sequential model.
- value_range
the range of values the incoming images will have. Represented as a two number tuple written (low, high). This is typically either
(0, 1)or(0, 255)depending on how your preprocessing pipeline is set up.- num_chains
an integer representing the number of different chains to be mixed, defaults to 3.
- chain_depth
an integer representing the maximum number of transformations to be applied in each chain. The actual number of transformations in each chain will be sampled randomly from the range
[0,chain_depth]. Defaults to 3.- factor
The strength of the augmentation as a normalized value between 0 and 1. Default is 0.3.
- alpha
a float value used as the probability coefficients for the Beta and Dirichlet distributions, defaults to 1.0.
- all_ops
Use all operations (including random_brightness, random_color_degeneration, random_contrast and random_sharpness). Default is True.
- interpolation
The interpolation method to use for resizing operations. Options include
"nearest","bilinear". Default is"bilinear".- seed
Integer. Used to create a random seed.
- data_format
string, either
"channels_last"or"channels_first". The ordering of the dimensions in the inputs."channels_last"corresponds to inputs with shape(batch, height, width, channels)while"channels_first"corresponds to inputs with shape(batch, channels, height, width). It defaults to theimage_data_formatvalue found in your Keras config file at~/.keras/keras.json. If you never set it, then it will be"channels_last".- ...
For forward/backward compatability.
