Probabilistic tracking algorithms typically using linear structure to update the learning model. Such linear structure is not appropriate for long-term robust tracking as the occlusion and other challenging factors may interfere the processing of incoming frames. Recently a spatio-temporal context (STC) algorithm based on Bayesian framework has using the context information between the target and...
This paper investigates the distributed motion planning of multiple robot arms with limited communications in the presence of noises. To do this, a nonlinearly-activated noise-tolerant zeroing neural network (NANTZNN) is designed and presented for the first time for solving the presented distributed scheme online. Theoretical analyses and simulation results show the effectiveness and accuracy of the...
With the exploration of the World Wide Web, more and more entities are involved in various online applications, e.g., recommender systems and social network services. In such context, high-dimensional sparse matrices describing the relationships among them are frequently encountered. It is highly important to develop efficient non-negative latent factor (NLF) models for these high-dimensional sparse...
In this paper, a schedulability test is proposed for tree-shaped transactions with non-immediate tasks. A tree-shaped transaction is a group of precedence dependent tasks, partitioned on different processors, which may release several other tasks upon completion. When there are non-immediate tasks, tasks are not necessarily released immediately upon their predecessor's completion. The schedulability...
In this paper a new task model is proposed for scheduling analysis of dependent tasks in radio stations that embed a TDMA communication protocol. TDMA is a channel access protocol that allows several stations to communicate in a same network, by dividing time into several time slots. Tasks handling the TDMA radio protocol are scheduled in a manner to be compliant with the TDMA configuration: task...
In Advanced Audio Video coding Standard (AVS), the utilization of variable block size ranging from 16×16 to 8×8 in inter frame encoding improves the coding efficiency significantly compared with a fixed MB partition. Rate distortion optimization (RDO) is the best known mode decision method, but the corresponding extremely high computational complexity limits its application. This paper proposes an...
Water simulation and terrain change are both important aspects in computer graphics and useful in producing realistic interactive environment. We present a step to combine the two phenomena together. In our system terrain is carefully organized to make it can be modified easily. The water flow is calculated by the shallow water simulation, which is a 2D simplification of Navier-Stocks equations. When...
This paper deals with the rendering issues of producing a realistic surgery simulation in real-time. In general, the visual fidelity of the simulator determines the degree of realism experienced by users. On top of the tissue, there is a mucous layer which is wet and semi-transparent. It significantly influences the surface appearance by reflecting and scattering incoming light rays. This paper describes...
