ClikaRT::ops::grid_sample

function

grid_sample()

Tensor grid_sample(
    Tensor x,
    Tensor grid,
    GridSampleMode mode = GridSampleMode::Bilinear,
    GridSamplePaddingMode padding_mode = GridSamplePaddingMode::Zeros,
    bool align_corners = false
)

Samples a channels-last input at arbitrary grid coordinates.

x [N, spatial_in.., C]; grid [N, spatial_out.., S] with S the spatial rank, coordinates normalized to [-1, 1]. mode picks the interpolation (Bilinear / Nearest / …), padding_mode the out-of-range policy (Zeros / Border / Reflection), align_corners the corner convention.

Parameters

• x: channels-last input.
• grid: normalized sample coordinates.
• mode: interpolation. Default GridSampleMode::Bilinear.
• padding_mode: out-of-range policy. Default GridSamplePaddingMode::Zeros.
• align_corners: corner convention. Default false.

Throws

• ClikaRT::Error: when the input's dtype/shape is not served for this operation (the machine-readable reason rides code_name()).

Returns: [N, spatial_out.., C], dtype of x.
