As an alternative to the watermarking approach, content-based copy detection (CBCD) recently has become a promising technique for video monitoring and copyright protection. In this paper, a novel CBCD framework is proposed. Firstly, robust global feature (DCT), local features (SIFT) and audio feature (EDF) are first combined to describe video and audio(More)
In this paper, we present a new variations of the popular nonnegative matrix factorization (NMF) approach to extend it to the data with negative values. When a NMF problem is formulated as X ≈ HW, we try to develop a new method that only allows W to contain nonnegative values, but allows both X and H to have both nonnegative and negative values. In(More)
Gossip-based protocols for group communication have attractive scalability and reliability properties. In this paper, we extend our previous work: a gossip-based protocol that enables agents to reach a consensus based on a special uninorm aggregation operator. We theoretically analyze the convergence and the randomness features of the extensions. The(More)
Palmitic acid (PA) is known to cause cardiomyocyte dysfunction. Cardiac hypertrophy is one of the important pathological features of PA-induced lipotoxicity, but the mechanism by which PA induces cardiomyocyte hypertrophy is still unclear. Therefore, our study was to test whether necroptosis, a receptor interacting protein kinase 1 and 3 (RIPK1 and RIPK3-)(More)
In this paper, we describe BUPT-MCPRL systems for TRECVID 2011. Our team participated in five tasks: semantic indexing, known-item search, instance search content-based copy detection and surveillance event detection. A brief introduction is shown as follows: In this year, we proposed two different methods: one based on text and another is bio-inspired(More)
Algebraic-geometric (AG) codes have long been considered as a possible candidate to replace Reed-Solomon (RS) codes. However, their decoding remains complex and infeasible to implement. Addressing this challenge, our paper proposes a low-complexity Chase (LCC) decoding algorithm for the most popular class of AG codes - Hermitian codes. The LCC decoding is(More)
Since how to quickly and accurately set the optimal process parameter of each mill in the cold rolling production process is an important base task for energy saving technology of cold rolling process now, this task designed a cold rolling process operation optimization simulation system based on Visual C++ and HMI software. Its design idea, system(More)
With the large computation quantity, long computing time and low real-time performance, the optical flow is not fit for the complex surroundings. The background image difference is only fit for the still background and so far, no reasonable approach has been designed and implemented for automatic background updating along with the background variance. To(More)
