Thresholding is an efficient technique for image segmentation. Otsu is frequently used in digital image processing. Two-dimensional Otsu threshold algorithm has been proposed based on Otsu algorithm. This paper gives an improved two-dimensional Otsu segmentation method which changes the coordinate system of the two-dimensional histogram to strengthen(More)
In this paper, we propose a Fuzzy-PID composite parameters' controller. Fuzzy control based on human language and habits of mind belongs to Intelligent Control, is applicable in automatic control field in complex system without accurate mathematic model. However, general fuzzy controller has steady-state static error. While PID can eliminate static error(More)
When using the Ah counting method to estimate state of charge of battery on electric vehicle, it is difficult to measure the initial SOC, and will bring accumulated errors. In order to solve the above problem, we design an algorithm which integrates the open circuit voltage method (OCV), Kalman filter (KF) and Ah counting method (Ah) in this paper. With the(More)
Adaptive median filtering method was mainly used for filtering Salt&Pepper (impulse) noise, while the method based on Curvelet transform was mainly used for filtering Gaussian noise. In the actual processing for sealed rubber ring image, which usually contains the mixture of Salt&Pepper noise and Gaussian noise. In order to filter out the mixed(More)
In multi-agent systems, agents are inclined to form coalitions to improve individual performance and perform tasks more efficiently. However, the most existing researches assume that the desired outcome is a coalition structure that consists of disjoint coalitions where every agent that has joined a coalition is no longer available to join other coalitions,(More)
The sophisticated computerized embroidery machine controller is urgently needed in embroidery industry. We designed a kind of scheme with dual-core processor to implement its function. The controller can be divided into two parts, the host computer part takes S3C2410X as its core controller, it fulfills function of network, graphic user interface and etc(More)
Non-subsampled Contourlet transform(NSCT) with translational invariance was applied to image denoising, which could capture the intrinsic geometrical structure of bottle image. After the scale of NSCT is determined, using NSCT to transform the noisy image of glass bottle. A low frequency component and some high frequency components will be obtained. Through(More)
In this paper a new image denoising algorithm is presented based on independent component analysis(ICA) and nonsubsampled contourlet transform(NSCT), taking full advantage of NSCT's strong points of translation-invariant, multidirection-selectivity and ICA's strong point of higher order statistical property, then a noisy image is denoised by maximum(More)
—In this paper, we propose a computerized embroidery This paper proposes a new scheme of computerized machine's controller based on ARM and DSP, which divides the embroidery machine's controller. According to the whole system into two modules. The main control module based performance index of the machine, our controller is based on on Samsung S3C2410X,(More)
