The invention relates to a method for determining an image centroid of a small irregular celestial body for deep space autonomous navigation. According to the method, a centroid coordinate system is determined according to a small celestial body three-dimensional shape model generated by ground data,...
The power loss and voltage distribution of distribution network are closely related to the site and size of DG and the load distribution. A new method of DG optimal placement is proposed based on load centroid. The district DG supplied is thought as an irregular shape load block and the load...
The video signals from camera 18 are also applied to an input amplifier 44 of the processing section 12 through a target contrast selection switch 46. The plurality of the output signal of the amplifier 44 (inverted or not) is determined by the position of switch 46. The output signal from...
The PointNet++ network is an end-to-end learning network for irregular point data and highly robust to small perturbations of input points along with corruption. It eliminates the need to calculate costly handcrafted features and provides a new paradigm for 3D understanding. However, each local ...
of Subcellular StructuresQing Yang, Member, IEEE, and Bahram Parvin, Senior Member, IEEEAbstract—Two novel computational techniques, harmonic cutand regularized centroid transform, are developed for segmen-tation of cells and their corresponding substructures observedwith an epi-f l uorescence microscope...
Two novel computational techniques, harmonic cut and regularized centroid transform, are developed for segmentation of cells and their corresponding substructures observed with an epi-fluorescence microscope. Harmonic cut detects small regions that correspond to small subcellular structures. These regions also...
Shape ApproximationIn this paper we propose a remeshing algorithm for altering the mesh geometry and connectivity of a 3D model to improve its uniformality. The new remeshing algorithm replaces an arbitrarily structured 3D mesh with a uniformly structured one, which has a given number of vertices,...
The main idea of UCDnet is to construct an infrared small target detection network that achieves dense prediction and sub-pixel-level centroid localization. Its network structure is shown in Figure 2 and consists of two parts: the semantic segmentation subnet and the centroid localization subnet. ...
