calculate_channel_abandonment
(chmap, basevalues, time_window)¶ Calculate channel abandonment.
Measure the number of channelized pixels that are no longer channelized as a signature of channel mobility based on method in Liang et al 2016. This requires providing an input channel map, and setting parameters for the min/max values to compare to, and the time window over which the evaluation can be done.
 Parameters
chmap (ndarray) – A txy shaped array with binary channel maps
basevalues (list) – A list of values (t indices) to use for the base channel maps
time_window (int) – Number of time slices (t values) to use for the transient maps
 Returns
PwetA – A 2D array of the abandoned fraction of the channel over the window of time. It is of shape len(basevalues) x time_window so each row represents the fraction of the channel that has been abandonded, and the columns are associated with each time lag.
 Return type
ndarray
