With the aim of improving the efficiency and perceptual quality in video coding, this paper proposes a novel just-noticeable coding distortion (JNCD) model that considers human visual perception redundancy and unreasonable factors of existing just-noticeable distortion (JND) models in the coding process. First, we design a psycho-physical experiment to analyze the just-noticeable gradient difference...
In this brief, a new tracking control algorithm for a class of networked control systems (NCSs) with non-Gaussian random disturbances and delays is proposed. Due to non-Gaussian random noises involved in the systems, solely controlling the expected value of the linear quadratic performance index is insufficient to obtain a satisfactory optimal control algorithm. The proposed method in this note applies...
With the tendency of population aging continues in our nation, problems associated with the elderly become major concerns in our society. If daycare centers for seniors can be established to care for the elderly just like daycare facilities for caring pre-school age children, seniors will have a place to enjoy day-time activities and return home to enjoy normal family life. The senior center that...
On the basis of N-S equations for solving three-dimensional Reynolds problem, k-ε turbulence model and standard wall function for near wall region were adopted. The region was meshed and boundary conditions were given. The software of computational fluid dynamics (CFD) was used to simulate centrifugal fan in the system of lignite quality improved. The parameters of static pressure, moving pressure,...
Multi-view video is a new multimedia service which provides interactive experience and depth perception. Color variations between the camera views are necessary to be eliminated in multi-view imaging. In this paper, a dominant color tracking based color correction method for multi-view video is proposed using Kalman filter. It tracks the dominant colors by using Kalman filter to fit the color variation...
Bar-headed geese (Anser indicus) is one of important migratory goose's species group around Qinghai lake region, the population dynamics of which is essential to decision-making of Bar-headed geese's protection in Qinghai lake National Nature Reserve. A bar-headed goose population dynamics model was developed using STELLA modeling tool in Qinghai lake region. The parameters included in the model that...
A physically based distributed model with incompact structure is built up by combining the advantages of the conceptual distributed model and the physically based distributed model. Its runoff generation module is based on the improved Green-Ampt infiltration theory, and its runoff concentration module is based on the concentration theory of geomorphological hydrology. In this model, the runoff generation...
Human-computer interaction (HCI) mode between terminal users and multiview video system (MVS) can directly affect the performance of MVS. User and video content factors to HCI mode are studied in this literature. Practical probability parameters are derived to evaluate random accessibility performance of MVS and multiview video coding schemes.
