random_zoom( x, zoom_range, row_axis=1, col_axis=2, channel_axis=0, fill_mode='nearest', cval=0.0 )
Defined in tensorflow/contrib/keras/python/keras/preprocessing/image.py
.
Performs a random spatial zoom of a Numpy image tensor.
Arguments:
x: Input tensor. Must be 3D. zoom_range: Tuple of floats; zoom range for width and height. row_axis: Index of axis for rows in the input tensor. col_axis: Index of axis for columns in the input tensor. channel_axis: Index of axis for channels in the input tensor. fill_mode: Points outside the boundaries of the input are filled according to the given mode (one of `{'constant', 'nearest', 'reflect', 'wrap'}`). cval: Value used for points outside the boundaries of the input if `mode='constant'`.
Returns:
Zoomed Numpy image tensor.
Raises:
ValueError: if `zoom_range` isn't a tuple.
