Public Functions Documentation¶

function DecompositionSize¶

size_t drift::DecompositionSize (
    const WaveletParameters & parameters
)

Estimate number of subbands for specific parameters

Parameters:

parameters

Returns:

function Distance¶

DataType drift::Distance (

Note:

The buffers must have the same number of decomposition steps otherwise the function returns NaN

Returns:

distance value 0 both buffers the same, 1 both buffers absolutely different

Parameters:

buffer source of subbunds

Returns:

vector of vector of the energies , layout is the same with WaveletBuffer
