We propose Geometry Prior guided Shadow generation Diffusion model (GPSDifffusion), which significantly improves the shadow geometry. The visual comparision between SGDiffusion and our GPSDiffusion is shown below. From left to right, we show the composite image, foreground mask, the result of SGDiffusion, the result of our GPSDiffusion, and ground-truth.
GPSDiffusion has been integrated into our image composition toolbox libcom.
The full code will be released upon the acceptance of paper.
