PT Journal AU Fadi Dornaika Angel Sappa TI Instantaneous 3D motion from image derivatives using the Least Trimmed Square Regression SO Pattern Recognition Letters JI PRL PY 2009 BP 535–543 VL 30 IS 5 DI 10.1016/j.patrec.2008.12.006 AB This paper presents a new technique to the instantaneous 3D motion estimation. The main contributions are as follows. First, we show that the 3D camera or scene velocity can be retrieved from image derivatives only assuming that the scene contains a dominant plane. Second, we propose a new robust algorithm that simultaneously provides the Least Trimmed Square solution and the percentage of inliers-the non-contaminated data. Experiments on both synthetic and real image sequences demonstrated the effectiveness of the developed method. Those experiments show that the new robust approach can outperform classical robust schemes. ER
