摘要： A method for encoding vertex orientations, also known as normal components, of a 3D mesh model comprises a first clustering of the normal components, determining for each of the first clusters a sphere sector to which most of its elements belong, mapping normal components to a predefined sector, re-clustering the normal components in the predefined sector into second clusters, determining predictors for the second clusters and encoding a normal component by its residual, a reference to its predictor and data indicating which of said mirror mapping operations were performed. A sphere sector is obtained by dividing a sphere into m equal spherical segments and dividing each of said spherical segments into n equal sectors. The first clustering for the sector mapping and the second clustering for predictive coding result in an improved compression ratio.

摘要： The invention is related to a method and a device for encoding of a bit sequence. Said method comprises generating, for each run of Ones comprised in the bit sequence, a unary representation of length of the respective run of Ones, generating a first sequence by concatenating the generated unary representations of lengths of runs of Ones, generating, for each run of Zeroes comprised in the bit sequence, a unary representation of the length of the respective run of Zeroes, generating a second sequence by concatenating the generated unary representations of lengths of runs of Zeroes, and bit plane encoding the generated first and second sequence of unary representations. In most cases, overall entropy of bit planes of unary representations of run lengths is smaller than entropy of the bit sequence. Thus, more compact encoding can be achieved.

摘要： A system and method for minimizing interference for mobile devices in a communication network that includes a macrocell base station and a femtocell having a base station. The method receives initialization data on a backhaul connection between the femtocell base station and the macrocell base station, and uses that data to configure the femtocell base station transmitting power. The method receives a user equipment identifier from a macrocell user equipment in the communication network, and determines whether the macrocell user equipment is authorized. If authorized, the macrocell user equipment is granted access to the femtocell base station. If unauthorized, user equipment information for the macrocell user equipment received on the backhaul connection is used to adjust the femtocell base station transmitting power to minimize the interference for mobile devices.
