Non-line-of-sight imaging has attracted more attentions for its wide applications. Even though ultrasensitive cameras/detectors with high time-resolution are available, current back-projection methods still powerless to acquire a satisfying reconstruction of multiple hidden objects due severe aliasing artifacts. Here, novel method is developed reconstruct objects. Our considers decomposing all the ellipsoids in confidence map into several "clusters" belonging different (namely "ellipsoid mode decomposition"), and then reconstructing individually from their ellipsoid modes by filtering thresholding, respectively. Importantly, simulated experimental results demonstrate that this can effectively eliminate impacts artifacts exhibits potential advantages separating, locating recovering objects, which might be good base complex non-line-of-sight scenes.
