pysap.extensions.formating.inflated_undecimated_n_bands(trf)[source]¶

Inflated the decomposition coefficients from a vector to a ‘cube’. ‘inflated_undecimated_n_bands’ concern the vector 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

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

coefficients.

Returns

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