To solve the problem of the “soft-field” effect and the proximity of sensitivity matrix in electrical capacitance tomography technology, an image reconstruction algorithm based on least squares support vector machine (LS-SVM) and particle swarm optimization (PSO) has been developed, namely LSP algorithm. Group image samples of some typical flow patterns are trained, and the capacitance deviation generated by the proximity of the sensitivity matrix is predicted. On the basis of the deviation, the fitness function in particle swarm optimization is established. The nonlinear adjustment method for inertia factor and the mutation operation of particles speed are used in the standard particle swarm optimization. The improved PSO algorithm is used to search for the optimal solution of the reconstructed image. The simulation shows that compared with Landweber algorithm, the image precision of LSP algorithm is improved nearly 50%, and the image error decreases to less than 20% for some typical flow patterns. Therefore, LSP algorithm can be applied to the non-real-time ECT system with high precision. This paper presents a feasible and effective way to research on image reconstruction algorithm for ECT. © 2016 ICIC International.

Sorted block's compensated difference based moving object detection

引用

ICIC Express Letters 2012年第7期6卷 1741-1746页

作者： Zhu, Juanjuan Guo, Baolong Institute of Intelligent Control and Image Engineering Xidian University No. 2 South Taibai Road Xi'an 710071 China

A fast moving object detection algorithm is presented based on sorted block's compensated difference. First, global motion estimation is applied based on feature points matching. The iteration of minimum sum of place error is employed to improve accuracy. Then, the current frame is warped to realize background compensation. Finally, the adaptive blocks' difference is computed between the compensated current frame and reference. The segmentation is accomplished gradually as the block is judged with the threshold and divided into four sub-blocks. Experimental results show that the algorithm can detect moving objects in complex video sequences with camera scan and dithering. The precision of motion detection is 0.5pixel and the processing speed achieves 30fps. © 2012 ICIC International.

Open Cybernetics and Systemics Journal 2014年第1期8卷 72-76页

Using reasonable and efficient autonomous technology for path planning can effectively improve the safety of ship navigation and can reduce human errors of maritime accidents. The planned path by A* algorithm is flawed with broken lines, many turning points and numerous transitional frequencies under the environment modeled by grid method. Smoothing A* algorithm is adopted to delete the removable points which prolong the planned path length. After all the realities of ship navigation are taken into account, smoothing A* algorithm is applied to resolve safe navigation problem for the ship. With the proposed smoothing A* algorithm, simulation results show that the conflict-free path can be planned for ships under different circumstances with static and dynamic obstacles and abide by the COLREGS. © Ma et al.;Licensee Bentham Open.

Augmented reality is the merging of synthetic sensory information into a user's perception of a real environment. As one of the most important tasks in augmented scene modeling, terrain simplification research has gained more and more attention. In this paper, we mainly focus on point selection problem in terrain simplification using triangulated irregular network. Based on the analysis and comparison of traditional importance measures for each input point, we put forward a new importance measure based on local entropy. The results demonstrate that the local entropy criterion has a better performance than any traditional methods. In addition, it can effectively conquer the 'short-sight' problem associated with the traditional methods.

Because of wide variation in gray levels and particle dimensions and the presence of many small gravel objects in the background, as well as corrupting the image by noise, it is difficult o segment gravel objects. In this paper, we develop a partial entropy method and succeed to realize gravel objects segmentation. We give entropy principles and fur calculation methods. Moreover, we use minimum entropy error automaticly to select a threshold to segment image. We introduce the filter method using mathematical morphology. The segment experiments are performed by using different window dimensions for a group of gravel image and demonstrates that this method has high segmentation rate and low noise sensitivity.

Novel image retrieval method based on interest points

Traditional interest points based image retrieval methods employed local features of interest points to describe image. The difference between local areas of interest points and the region of interest limited the retrieval accuracy. Considering the shape characteristic of interest points, this paper presented a new image retrieval method based on region of interest determined by interest points. Firstly, interest points were detected by tracking wavelet coefficients of different scales. Secondly, the convex hull of interest points was calculated to extract the region of interest in the image. Then color and shape features of the region were used to describe an image. Finally, the weighted feature distance was used to define the similarity between two images. With robustness to image rotation, translation and scale, the method makes the retrieval implementation at the object level and avoids the shortcoming of traditional methods. Lots of experiments based on an image database containing 1100 images show that the method improves the average retrieval precision over 11.1 percent, compared with other interest points based retrieval methods.

A variant of spiking neural P systems was recently investigated by the authors, using astrocytes that have excitatory and inhibitory influence on synapses. In this work, we consider this system in the non-synchronized (i.e., asynchronous) mode: in any step, when a neuron is enabled, it is not obligatorily fired, making a global clock dispensable. It is proved that asynchronous spiking neural P systems with astrocytes are universal (when using extended rules). The construction is uniform in the sense that the form of the modules used is independent of the simulated register machine. © 2012 Springer-Verlag.

In order to solve the problem of under-segmentation in traditional superpixel methods, a new image segmentation framework is proposed, which is based on gradient ascent including Simple Linear Iterative Clustering (SLIC) superpixels and watershed algorithm. First, SLIC method is adopted to generate uniform superpixels, which are then determined whether under-segmentation occurs by a homogeneity criterion. In heterogeneous regions, an adaptive watershed algorithm processes a more precise division based on luminance histogram. Experimental results show that the bi-level framework has good performance on detail-rich regions, without significantly increasing the time complexity compared with conventional SLIC. © 2019, Springer Nature Singapore Pte Ltd.
