2results about How to "Convenient registration" patented technology

A method for performing registration in a low-power device (LPD) to a wireless network, the method comprising: broadcasting (705) a first uplink UL message indicating a registration request, the message including the ID of the LPD in the wireless network; receiving (710) an acknowledgment from at least one communication node, the acknowledgment including the node ID of the communication node that received the first UL message; and determining (715) an initial network topology based on the acknowledgment.

The application relates to a multi-expression face homotopy mesh data acquisition method and device and electronic equipment, which comprises the following steps: obtaining dense semantic information of a face from an original face database, calculating first dense optical flow between different expression viewgraphs under different view angles, deforming the vertices of each expression mesh based on the first dense optical flow and a multi-view positioning method, obtaining a preliminary semantic-consistent enhanced expression mesh, then calculating second dense optical flow between UV graphs of each expression mesh, and correcting the coordinates of the vertices of each expression mesh based on the second dense optical flow, thereby obtaining strong semantic-consistent multi-expression face homotopy mesh data. Thus, semantic information is acquired from original face acquisition data, semantic relationships between expressions are constructed by using optical flow, and the semantic consistency of separately registered multi-expression mesh data is enhanced, so that the problems of multi-expression face mesh data of the same individual obtained by a separate registration method and semantic inconsistency between expressions are solved.
