Web22 de abr. de 2024 · From a pair of the synthetic GRS images, the velocity field is extracted using OFM (OpenOpticalFlow) (Liu 2024), resulting in 900 × 1200 velocity vectors. Figure 18 a, b shows the velocity vector and normalized velocity magnitude fields extracted by OFM, respectively, where the fields are downsampled for clear illustration.
