Hi, I do not find “makeCorresDataset” in 3dmatch-toolbox？ In addition， I want to use mxnet to train my net with TDF. But I don't known how to input TDF to my net？ thanks！

makeCorresDataset.m can be found in evaluation/keypoint-matching/makeCorresDataset.m

The code from this repository saves TDF voxel grids as a flattened array of float values. You can read those into your MXNet data loader and convert/reshape your TDF into a 3-dimensional array (numpy.ndarray object), convert it into an MXNet NDArray, and pass it into your net (refer to here). Code to compute TDF from mesh, or depth images, 3D point clouds, can be found here.
