TY - JOUR AU - Mikhail Mozerov AU - Fei Yang AU - Joost Van de Weijer PY - 2019// TI - Sparse Data Interpolation Using the Geodesic Distance Affinity Space T2 - SPL JO - IEEE Signal Processing Letters SP - 943 EP - 947 VL - 26 IS - 6 N2 - In this letter, we adapt the geodesic distance-based recursive filter to the sparse data interpolation problem. The proposed technique is general and can be easily applied to any kind of sparse data. We demonstrate its superiority over other interpolation techniques in three experiments for qualitative and quantitative evaluation. In addition, we compare our method with the popular interpolation algorithm presented in the paper on EpicFlow optical flow, which is intuitively motivated by a similar geodesic distance principle. The comparison shows that our algorithm is more accurate and considerably faster than the EpicFlow interpolation technique.
