Similar to Matlab's interp2 function.

tfa.image.interpolate_bilinear(
    grid,
    query_points,
    indexing='ij',
    name=None
)

Finds values for query points on a grid using bilinear interpolation.

Args:

  • grid: a 4-D float Tensor of shape [batch, height, width, channels].
  • query_points: a 3-D float Tensor of N points with shape [batch, N, 2].
  • indexing: whether the query points are specified as row and column (ij), or Cartesian coordinates (xy).
  • name: a name for the operation (optional).

Returns:

  • values: a 3-D Tensor with shape [batch, N, channels]

Raises:

  • ValueError: if the indexing mode is invalid, or if the shape of the inputs invalid.
