We present a framework for the compression of flow fields based on edge-aware homogeneous diffusion inpainting. Our method benefits from the piecewise smooth structure of motion fields by storing additional edge information for the inpainting process. [15] stores mask pixels on both sides of edges and uses homogeneous diffusion inpainting to reconstruct smooth regions in-between. The centrepiece of our codec is the edge-aware homogeneous diffusion that is used to reconstruct a flow field with only a small amount of known data. Our edge-aware homogeneous inpainting algorithm also requires a set of mask points to be able to reconstruct a flow field. Comparison of JPEG2000, BPG, and our edge-aware approach for two flow fields and a compression ratio of 400 : 1.	./cache/cord-178421-tl4qtz2x.txt	./txt/cord-178421-tl4qtz2x.txt
