A continuous linear optimal transport approach for pattern analysis in image datasets

作者:

Highlights:

• A continuous version of the LOT framework is described that bypasses many of the difficulties associated with the discrete formulation.

• Using continuous transport maps, a forward and inverse transform operation is defined for images.

• An improved reference/average image estimation algorithm is proposed.

• The range within which points in LOT space are invertible according to the continuous formulation is calculated.

• We show that our method significantly speeds up the computation of the LOT embedding.
