Similar to Matlab's interp2 function.

img_interpolate_bilinear(grid, query_points, indexing = "ij", name = NULL)

Arguments

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).

Value

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

Details

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

Raises

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