Recent advances on 3D object detection heavily rely how the data are represented, i.e., voxel-based or point-based representation. Many existing high performance detectors because this structure can better retain precise point positions. Nevertheless, point-level features lead to computation overheads due unordered storage. In contrast, is suited for feature extraction but often yields lower ac...

At the typical spatial resolution of MRI in human brain, approximately 60–90% voxels contain multiple fiber populations. Quantifying microstructural properties distinct populations within a voxel is therefore challenging but necessary. While progress has been made for diffusion and T1-relaxation properties, how to resolve intra-voxel T2 heterogeneity remains an open question. Here novel framewo...

To model a true three-dimensional (3D) display system, we introduced the method of voxel molding to obtain stereoscopic imaging space system. For distribution each voxel, proposed four-dimensional (4D) ... | Find, read and cite all research you need on Tech Science Press
