论文采用了基于voxel的方法(voxel feature encoding (VFE) module),先将点云数据划分成voxel,然后用VFE网络提取特征。每个voxel就相当于transformer中的一个token。考虑到transformer充足的感受野,和户外检测物体的尺寸都比较小,论文采用single-stride的网络设计。不会减少feature
It first converts the input point clouds into sparse voxels by a voxel feature encoding (VFE) module, like previous voxel-based methods [37, 45, 48]. Each voxel will be treated as a "token". Considering the sufficient receptive field of transformer and the tiny scale of...
We used the classifiers trained in the touch localization interval to classify voxel patterns in the movement planning interval66. Successful cross-interval classification would suggest that tactile stimulus coding was maintained across both touch localization and movement planning intervals. In contrast, a...

The voxel feature fvoxeli ∈ Rh∗l is the hidden feature of neural voxels. and we utilize bilinear interpolation to interpolate the four nearby queried voxel features. 体素特征 fvoxi ∈ Rh∗l 是神经体素的隐藏特征。我们利用双线性插值对四个附近的查询体素特征进行插值。 In the compact represent...
interpolation) followed by head motion correction (using mutual information). Data was afterwards co-registered to the T2-weighted anatomical images, normalized to a reference animal and smoothed using a 3D Gaussian isotropic kernel with a full-width half-maximum corresponding to 1 voxel (0.268 ...
In data acquisition procedure (400), sensor data is received, and the MLA generates, based on the sensor data, a set of feature vectors output by a voxel encoding procedure (500) for a given voxel of a set of voxels, the voxel procedure (500) receiving a LIDAR point cloud of a set ...
Total lesion volume was calculated as the sum of lesioned voxel (voxel size = 1 mm3) divided by 1000 to achieve units in ml. Total lesion volume served as a control variable in the statistical analyses explained below. Structural connectome processing ...
405 frames were acquired in each session using multiband, gradient-echo planar imaging with the following parameters: TR = 720 ms; TE = 33.1 ms; flip angle = 52°; field of view = 280 × 180 mm; matrix = 140 × 90; and voxel dimensions =...
memory or storage devices of claim 11, wherein the encoding further comprises applying one or more voxel-distortion-correction filters to the three-dimensional image data for the current frame, the one or more voxel-distortion-correction filters being applied in-loop during inter-frame encoding. ...
