MURI Group Proposes New Framework for In-Between Imagery

The work of former postdoc Dr. Han with professors Lee and Gelb, "Learning in-between imagery dynamics via physical latent spaces”, has been published in the SIAM Journal on Scientific Computing. The work proposes a framework to learn the underlying dynamics between two images observed at consecutive time steps. The proposed method focuses on estimating the intermediary stages of image evolution, allowing for interpretability through latent dynamics while preserving spatial correlations with the image. By incorporating a latent variable that follows a physical model expressed in partial differential equations, the approach ensures the interpretability of the learned model and provides insight into corresponding image dynamics. The work also provides a series of numerical tests, including real SAR data, to demonstrate the robustness and effectiveness of the new framework. Click the video below for higher resolution. More demonstrations (including videos) can be found here.
