Resampler
Description
Resamples input data at user defined coordinates.
Usage
img_resampler(data, warp, name = NULL)
Arguments
data |
Tensor of shape [batch_size, data_height, data_width, data_num_channels] containing 2D data that will be resampled. |
warp |
Tensor of minimum rank 2 containing the coordinates at which resampling will be performed. Since only bilinear interpolation is currently supported, the last dimension of the warp tensor must be 2, representing the (x, y) coordinate where x is the index for width and y is the index for height. |
name |
Optional name of the op. |
Details
The resampler currently only supports bilinear interpolation of 2D data.
Value
Tensor of resampled values from 'data'. The output tensor shape is determined by the shape of the warp tensor. For example, if 'data' is of shape '[batch_size, data_height, data_width, data_num_channels]' and warp of shape '[batch_size, dim_0, ... , dim_n, 2]' the output will be of shape '[batch_size, dim_0, ... , dim_n, data_num_channels]'.
Raises
ImportError: if the wrapper generated during compilation is not present when the function is called.
