- class MinMaxTransformer[source]#
Transforms chips by scaling values in each channel to span 0-255.
- transform(chip: ndarray, channel_order: Optional[List[int]] = None) ndarray [source]#
Transform a chip of a raster source.
chip (ndarray) – ndarray of shape [height, width, channels] This is assumed to already have the channel_order applied to it if channel_order is set. In other words, channels should be equal to len(channel_order).
channel_order (Optional[List[int]]) – list of indices of channels that were extracted from the raw imagery.
[height, width, channels] numpy array
- Return type
