Class Cropping3D

Cropping layer for 3D data (e.g. spatial or spatio-temporal).

Inherits From: Layer

Arguments:

  • cropping: Int, or tuple of 3 ints, or tuple of 3 tuples of 2 ints.
    • If int: the same symmetric cropping is applied to depth, height, and width.
    • If tuple of 3 ints: interpreted as two different symmetric cropping values for depth, height, and width: (symmetric_dim1_crop, symmetric_dim2_crop, symmetric_dim3_crop).
    • If tuple of 3 tuples of 2 ints: interpreted as ((left_dim1_crop, right_dim1_crop), (left_dim2_crop, right_dim2_crop), (left_dim3_crop, right_dim3_crop))
  • data_format: A string, one of channels_last (default) or channels_first. The ordering of the dimensions in the inputs. channels_last corresponds to inputs with shape (batch, spatial_dim1, spatial_dim2, spatial_dim3, channels) while channels_first corresponds to inputs with shape (batch, channels, spatial_dim1, spatial_dim2, spatial_dim3). It defaults to the image_data_format value found in your Keras config file at ~/.keras/keras.json. If you never set it, then it will be "channels_last".

Input shape:

5D tensor with shape: - If data_format is "channels_last": (batch, first_axis_to_crop, second_axis_to_crop, third_axis_to_crop, depth) - If data_format is "channels_first": (batch, depth, first_axis_to_crop, second_axis_to_crop, third_axis_to_crop)

Output shape:

5D tensor with shape: - If data_format is "channels_last": (batch, first_cropped_axis, second_cropped_axis, third_cropped_axis, depth) - If data_format is "channels_first": (batch, depth, first_cropped_axis, second_cropped_axis, third_cropped_axis)
