create_tmp_data_interlace_dates()

template<typename PixelType >

std::tuple<PixelType, PixelType, PixelType > GapFilling::create_tmp_data_interlace_dates ( const PixelType  pix, const PixelType  mask, const PixelType  idv, const PixelType  odv, typename PixelType::ValueType  valid_value  )

inline

Generate a new pixel and a corresponding mask after interlacing input and output dates. The resulting pixel values for the dates which were not available in the input have a nundefined value and are masked.

gapfill_time_series()

template<typename ImageType , typename FunctorType , typename MultiComponentFunctorType = MultiComponentTimeSeriesFunctorAdaptor<typename ImageType::PixelType, FunctorType>>

void GapFilling::gapfill_time_series	(	typename ImageType::Pointer	inIma,
		typename ImageType::Pointer	maskIma,
		typename BinaryFunctorImageFilterWithNBands< ImageType, ImageType, ImageType, FunctorType >::Pointer	filter,
		typename BinaryFunctorImageFilterWithNBands< ImageType, ImageType, ImageType, MultiComponentFunctorType >::Pointer	filter_mc,
		vcl_size_t	components_per_date = 1,
		typename ImageType::PixelType	dv = typename ImageType::PixelType{},
		typename ImageType::PixelType	odv = typename ImageType::PixelType{}
	)

The gapfill_time_series function takes 2 input time series files (the image data and the mask data) and produces an output file (the gapfilled image data). The number of components (spectral bands, for instance) per date can be provided (default is 1) so that the different components are processed as individual time series. A file containing the dates of the acquisition can be provided. It should contain one date per line in YYYMMDD format.

The mask time series is supposed to contain 0s for the valid dates. The function is templated over the ImageType (typically an otb::VectorImage<double,2>) and on the interpolating functor.

get_csv_profiles()

std::vector<VectorType> GapFilling::get_csv_profiles	(	const std::string &	fname,
		int	pos,

get_sirhyus_profiles()

std::vector<std::pair<long int, VectorType> > GapFilling::get_sirhyus_profiles	(	const std::string &	df,
