WebImage registration is the process of establishing a common geometric reference frame between two or more image data sets possibly taken at different times. In this paper we present a method for computing elastic registration and warping maps based on the Monge–Kantorovich theory of optimal mass transport. WebThe use of optimal transport distance has recently yielded significant progress in image processing for pattern recognition, shape identification, and histo- grams matching. In this study, the use of this distance is investigated for a seismic tomography problem exploiting the complete waveform; the full waveform inversion. how have deserts changed over time
