In this study, we have proposed an improved GreenWarps, which is based on the combination of prewarping using Green coordinates and robust elastic warping. Firstly, an unaligned image is warped to the reference image by Green coordinates, and then the prewarped image is warped and locally registered using robust elastic warping. Finally, seam estimation is implemented to seamlessly blend the registered warped and reference images together. The experimental results confirm that our method can effectively stitch images with large parallax and projection distortion, which is difficult to realize using the state-of-the-art methods.
