Most existing video denoising algorithms assume video noise to be additive Gaussian white noise, which is often impractical to deal with the mixed noises in reality. A robust video denoising algorithm is proposed in this paper to remove mixed Poisson, Gaussian and impulse noises from the video data. The denoising problem to remove mixed noises is formulated as a low rank and sparse video recovery...
The bathtub-shaped curve is essential in interpreting the failure rate function for the reliability analysis, and its parameters determine the representation of the bathtub-shaped function. This paper introduces a parameterised bathtub curve that provides an adaptive bathtub-shaped failure rate function (ABF) modelling approach which can be also easily utilised as a universal objective for further...
Reliability allocation problems of large systems become easier if the optimization model can be decomposed and solved as a set of smaller, coordinated sub-problems. A hierarchical structure for optimal reliability allocation based on target cascading is proposed in this paper. An example is given to illustrative the method.
Many systems are required to perform a series of missions with finite breaks or limited maintenance resources between successive missions. In such cases, one of the most widely used maintenance policies is a selective maintenance in which a subset of feasible maintenance actions is chosen to satisfy the subsequent mission requirements. Traditional selective maintenance optimization problems reported...
The paper directs the mathematical models of the sphere and the column obstacles for a redundant robot, which can be looked on as a reference for other complex shaped obstacles. Based on the models, the performance criterion function of obstacle avoidance is presented in light of artificial potential field method. Subsequently, through optimizing the performance criterion the simulation of obstacle...
