Gradient vector flow (GVF) has been one effective external force for active contours, but it is based on isotropic diffusion. The recently proposed NGVF external force just took into account the diffusion along normal direction of the level line, so it is sensitive to noise and could smear the weak boundaries. In this article, we present a novel one called normally biased gradient vector flow (NBGVF) which keeps the diffusion along the tangential direction of the level line and biases that along the normal direction. The biasing weight of the diffusion along the normal direction approaches zero at boundaries and is 1, even larger, in homogeneous regions. Consequently, the NBGVF can preserve weak edges and smooth out noise while maintaining other desirable properties of GVF and NGVF such as enlarged capture range, insensitivity to initialization and convergence to u-shape concavity. These properties are evaluated on synthetic and real images.

The gradient vector flow (GVF) is an effective external force for active contours, but it's smoothness constraint doesn't take any image structure into account and the resulting diffusion equation is isotropic which would oversmooth weak edges. In this article, a novel external force named image structure adaptive gradient vector flow (ISAGVF) is proposed for active contours. The proposed ISAGVF employs certain smoothness constraint which is able to be adaptive to image structure, such that the ISAGVF snake would outperform the GVF snake in terms of noise robustness, weak edge preserving and narrow and deep concavity convergence, while possessing some other desirable properties such as enlarged capture range and insensitivity to initialization. Experiments on synthetic and real images manifest these properties of ISAGVF snake.

A new external force called oriented smoothness aided harmonic gradient vector flow (OSAHGVF) is proposed for active contours. This proposed method incorporate the oriented smoothness borrowed from optical flow into the harmonic gradient vector flow (HGVF) model, therefore, there are three terms, i.e., the harmonic term, the oriented smoothness term and the fidelity term, in the model. Two weighting functions are utilized to regularize the effect of the first two terms respectively, aiming at extending the capture range and preserving object boundaries simultaneously. Experiments and comparisons with the gradient vector flow (GVF) are presented to show the advantages of this approach, including superior noise robustness, edge-preserving and C-shape concavity convergence.

The gradient vector flow (GVF) snake shows high performance at concavity convergence and initialization insensitivity, but the two components of GVF field are treated isolatedly during diffusion, this leads to the failure of GVF snake at deep and narrow concavity convergence and weak edge preserving. In this study, a novel external force for active contours is proposed that couples the two components during diffusion by generalizing the Laplacian operator from flat space to manifold. The specific operator is Beltrami operator. This proposed method has been assessed on synthetic and real images; experimental results show that the new method behaves similarly to the GVF snake in terms of capture range enlarging, initialization insensitivity, U-shape concavity convergence, while provides much better results than GVF snake for noise robustness, narrow and deep concavity convergence and weak edge preserving.

In order to get good fusion result for nomadic service under pervasive computing paradigm, based on our researches, we present a new approach of entropy-based wavelet filtering to do an adaptive soft process for nomadic decision, which is the good balance when considering both application quality and the PSNR criterion. Using a hard threshold-ing, a soft thresholding , MEF method, and MEF method with as a function of the SNR, wavelet coefficient can be modified . Our project has been provided evidence of feasibility of the a new approach.

To improve the convergence time of ant colony algorithm, avoid falling in local best and enhance the quality of solution, a novel dynamic parameters ant colony algorithm with particle swarm characteristics is proposed. Learning the multi-information instruction characteristic of Particle Swarm Optimization Algorithm, the global pheromone update rule with particle swarm characteristic is introduced to improve the directive function of pheromone and the speed of convergence. At the same time, solution multiplicity is guaranteed as far as possible. Using the function of current condition to update particle speed and position, parameters of Ant Colony Algorithm is used to reflect the current condition. Hyperbola Tangent function is imported to dynamic adjust parameters so that the relation between local search and global search could be balanced. Comparing with basic Ant Colony Algorithm, the simulation result on TSP shows that new algorithm has higher convergence speed and better solution.

Over the last two decades, many image processing problems have been modeled by partial differential equations (PDEs), such as restoration and segmentation. Due to good performance at controlling the trade-off between noise removal and edge-preserving, second-order PDEs play leading role in image restoration. The dilemma for second-order PDEs is the so-called staircasing effect. One remedy for this issue is the fourth-order PDEs, but the fourth-order PDEs suffer from the problem of oversmoothing the edges. In this paper, a novel PDE is proposed based on minimal surface and p(x) harmonic maps. The proposed model behaves like TV model at edge regions while like heat transfer equation within homogeneous regions. The proposed model is further projected to the normal direction of a smoothed version of the original image for the purpose of edge preserving. Several experiments have been conducted and promising results are observed.

For the actual need of future research and application, this paper proposes a new method that is a new fuzzy control system of fuzzy integral-genetic algorithm (FI-GA). By fuzzy integral, it can study comprehensive evaluation of population diversity and individual quantity on three attributes: individual difference extent, the difference extent of individual's fitness and the difference extent of population lifetime, thereby dynamically adjust the rate of crossover (Pc) and mutation rate (Pm) in genetic algorithm. It improves the controller of fuzzy control for parameters Pc and Pm of genetic algorithm. The results of experiment show that the proposed genetic algorithm, combining fuzzy measure and fuzzy integral, performances better than simple genetic algorithm (SGA).

The traditional method based on moving average filter can remove the baseline wander in electrocardiogram signals, but also causes the loss of motive ECG signals, which makes distortions of filtered ECG signals. In this paper, a modified moving average filter is proposed to selectively capture the low-frequency baseline wander noise and remove it from the detected signals in order to recover true ECG. The interval sampling data is taken into consideration when calculate the moving average in order to reduce the loss of useful ECG signals and distortions. The algorithm is developed for computer implementation using MATlab. To validate the proposed methods, the recording from MIT/BIH database is used. Experimental results demonstrate the improvement of the proposed moving average filter over the traditional one in removing baseline wander without introducing distortion to the ECG signals.
