The edge ringing artifacts often appear nearby the image edge for the deconvolution bias. PDE-based non-linear techniques are an effective way to process the image. So a new diffusion filtering is proposed to remove the edge ringing artifact in the deconvolution image based on PDE filter. The experimental results validate the proposed edge ringing artifact filtering algorithms perform well.
The edge ringing artifacts often appears near image edge after deconvolution. We presented an iterative enhancement algorithm to remove the edge ringing artifact. We also presented an edge ringing metric to evaluate the quality of images enhanced based on the human visual system. The metric is used to assessment the edge ringing artifact based on the analysis of the structure of it. The experimental...
Traditional Genetic Algorithm (GA) easily falls into local optimum and its speed of searching global optimum is very slow. Considering the cloud model has the characteristic of randomness and stability, a new hybrid algorithm (ACGA) based on asymmetrical cloud model and GA is proposed. ACGA use the asymmetrical y-conditional cloud model as cross operation, basic normal cloud generator as mutation...
Cloud model can be used for reliability evaluation when the working condition is changeable and described by the qualitative linguistic values. It is neglected that the most typical sample in cloud model also contains some uncertainty when evaluate the reliability of products using cloud model. For this reason, a cloud model is used to describe the uncertainty of the most typical sample. The experimental...
In this paper we proposed a new algorithm based on inver-over operator, for combinatorial optimization problems. Inver-over is based on simple inversion; however, knowledge taken from other individuals in the population influences its action. In the new algorithm we use some new strategies including selection operator, replace operator and some new control strategy, which have been proved to be very...
