Image warping using local homography
Did you know?
WitrynaIn contrast to using a single global homography warp to align the images, APAP [7] uses a spatially-varying warp H that consists of multiple local homography warps for image alignment. In other words, instead of using the common dominant plane to approximate the non-planar geometry of the scene, APAP uses the field of spatially … Witryna11 kwi 2024 · In particular, we generate MPIs (using the 3D CNN described above) from multiple sets of images that are close to the desired viewpoint, then use homography warping (i.e., this “warps” each MPI to the desired viewpoint) and alpha compositing (i.e., this combines the different warped MPIs into a single view) to produce an RGB …
