We introduce optimal transport-type distances for manifold- valued images. To do so we lift the initial data to measures on the product space of image domain and signal space, where they are compared using a transport cost that combines spatial distance and signal discrepancy. Applying recent ‘unbalanced’ optimal transport models leads to more natural results. We illustrate the benefit of the lifting with examples for interpolation of color images and classification of handwritten digits.
