Web4 aug. 2024 · A homography is a type of projective transformation in that we take advantage of projections to relate two images. Homographies were originally introduced to study shifts in perspective, and they have enabled people to better understand how images change when we look at them from a different perspective. WebWide-baseline street image interpolation is useful but very challenging. Existing approaches either rely on heavyweight 3D reconstruction or computationally intensive deep networks. We present a lightweight and efficient method which uses simple homography computing and refining operators to estimate piecewise smooth homographies between input …
