Most of overlapping community detection algorithms cannot be applied to networks with highly overlapping community such as online social networks where individuals belong to many communities. One important reason is that many algorithms detect communities based on the explicit borders where nodes have more connections inside the communities, however, when the vertices' membership number gets large,...
The high computational complexity and great memory requirement prevent the SIFT algorithm from being processed realtimely. The block-parallel SIFT algorithm with boundary extension adopted by existing researches suffers from redundant storages or extra communications to process the boundaries of partitions. The block-parallel SIFT algorithm without boundary extension (pSIFT-noBE) can spontaneously...
In this paper, we present an approach for detecting MTV video shot using Hidden Markov Models (HMMs), in which the color, shape and motion features are utilized. First, the temporal characteristics of different shot transitions are exploited and an HMM is constructed for shot transitions, including cut and gradual transitions. Secondly, a trained HMM are used to recognize the shot transition automatically,...
