tensorstore::Downsample(
TensorStore<Element, Rank, Mode> store,
std::type_identity_t<span<const Index, Rank>> downsample_factors,
DownsampleMethod downsample_method); Returns a downsampled view of a
TensorStore.- Parameters:¶
- TensorStore<Element, Rank, Mode> store¶
Base view to downsample, must support reading.
- std::type_identity_t<span<const Index, Rank>> downsample_factors¶
Factors by which to downsample each dimension of
store. Must have length equal tostore.rank()and all factors must be positive. Specifying a factor of 1 indicates not to downsample a given dimension. May be specified as a braced list, e.g.Downsample(store, {2, 3}, DownsampleMethod::kMean).- DownsampleMethod downsample_method¶
The downsampling method.
- Returns:¶
The downsampled view, with the same rank as
storebut downsampled domain.- Error absl::StatusCode::kInvalidArgument:¶
