In keras: R Interface to 'Keras'

Crop the central portion of the images to target height and width

Description

Crop the central portion of the images to target height and width

Usage

layer_center_crop(object, height, width, ...)

Arguments

object	What to compose the new Layer instance with. Typically a Sequential model or a Tensor (e.g., as returned by layer_input()). The return value depends on object. If object is: missing or NULL, the Layer instance is returned. a Sequential model, the model with an additional layer is returned. a Tensor, the output tensor from layer_instance(object) is returned.
height	Integer, the height of the output shape.
width	Integer, the width of the output shape.
...	standard layer arguments.

Details

Input shape: 3D (unbatched) or 4D (batched) tensor with shape: ⁠(..., height, width, channels)⁠, in "channels_last" format.

Output shape: 3D (unbatched) or 4D (batched) tensor with shape: ⁠(..., target_height, target_width, channels)⁠.

If the input height/width is even and the target height/width is odd (or inversely), the input image is left-padded by 1 pixel.
