pysap.extensions.formating.flatten_undecimated_n_bands(cube, trf)[source]¶

Flatten the decomposition coefficients from a ‘cube’ to a vector. ‘flatten_undecimated_n_bands’ concern the ‘cube’ where each layer correspond to a undecimated band. We can have multiple bands per scale, which lead to nb_scale * nb_band_per_scale for one dimension.

Parameters

cube : np.ndarray, the cube that containes the decomposition

coefficients.

Returns

data : np.ndarray, the flatten ‘cube’.
