Object detection problems-skin detection here can be considered as object recognition problems with two classes. In this paper, each given class is clustered using the Kmeans algorithm into multiple subclasses and a Multilayer perceptron (MLP) neural network (NN) is trained for each clusters separately. In the testing phase, each point is compared with centers of clusters and the network related to closest center is selected for each new cluster. Besides the system performance improvement, it also can significantly reduce the testing time. Then the Utans algorithm as a trained NNs-based feature selection method is applied to 44 color components of 15 different color spaces. The obtained results show that the presented algorithm compare to other algorithms has higher performance and less execution time as well.

In order to improve the performance of modulation classification systems, the idea of multi-receiver recognition has been developed recently. In this paper multiple receivers' collaboration at different information levels is investigated for classification of signals used in DVB-S2 standard. Three methods are proposed for receivers' cooperation at each one of signal, feature and decision levels. The proposed methods use cumulants and MLP neural network as signal features and classifier respectively. These methods are evaluated and compared through performance, complexity and equipment. The results show that receivers' cooperation at signal level offers more accurate classification compared to feature and decision levels, in addition to less computational complexity.

This paper presents a novel approach for the generation of 3D building model from IKONOS satellite image data. The main idea of 3D modeling is based on the grouping of 3D line segments. The divergence-based centroid neural network is employed in the grouping process. Prior to the grouping process, 3D line segments are extracted with the aid of the elevation information obtained by using area-based stereo matching of satellite image data. High-resolution IKONOS stereo images are utilized for the experiments. The experimental result proved the applicability and efficiency of the approach in dealing with 3D building modeling from high-resolution satellite imagery.

A novel three dimensional bi-directional self-organizing neural network (3-DBDSONN) architecture with fuzzy context sensitive thresholding suitable for three-dimensional (3D) imageprocessingapplications, is proposed in this article. The proposed architecture comprises three interconnected three-dimensional fuzzy layers of neurons. It is devoid of any back-propagation algorithms for weight adjustments. An application of extraction of three-dimensional binary objects from various degrees of noisy background is demonstrated on one synthetic and two real life three-dimensional binary voxelized images. The efficiency of the proposed network as regards to immunity to different types of noise indicates encouraging avenues.

Cell counts and classification of the cells play an important role in the field of microbiology and cell biology. Although there exists many counting processes for cells of interest in suspension, the most basic cell counting process is performed by a person via the microscope. For counting cells the simplest, widely used and the most economic method is the use of hemocytometer counting. In this study, the hemocytometer counting was used but the the cells were counted by a proposed image based approach. The developed technique herein uses neural network along with the Hough transform.

Developing mathematical model of a process or system from experimental data is known as empirical modeling. Traditional mathematical techniques are unsuitable to solve empirical modeling problems due to their nonlinearity and multimodality. So, there is a need of an artificial expert that can create model from experimental data. In this paper, we explored the suitability of neural Network (NN) and symbolic regression via Genetic Programming (GP) to solve empirical modeling problems and conclude that symbolic regression via GP can deal efficiently with these problems. This paper aims to introduce a novel GP approach to symbolic regression for solving empirical modeling problems. The main contribution includes: (i) a new method of chromosome representation (postfix based) and evaluation (stack based) to reduce space-time complexity of algorithm (ii) comparison of our approach with Gene Expression Programming (GEP), a GP variant (iii) algorithms for generating valid chromosomes (in postfix notation) and identifying non-coding region of chromosome to improve efficiency of evolutionary process. Experimental results showed that empirical modeling problems can be solved efficiently using symbolic regression via postfix GP approach.

In this paper, we propose an imageprocessing system for the detection of wildfire smoke based on computational intelligence techniques and capable of adapting to different applicative environments. The proposed system is designed for processing with limited computational complexity. The detection process focuses on the extraction of specific features of wildfire smoke. A computational intelligence classifier is adopted to identify the presence of smoke. In order to test its effectiveness, the proposed system has been tested with low quality frame sequences, providing the capability to deal also with low cost cameras. The results indicate that the proposed approach is accurate and can be effectively applied in different environmental conditions.

Accurate segmentation of cell nuclei in microscope images of tissue sections is a key step in a number of biological and clinical applications. Often such applications require analysis of large image datasets for which manual segmentation becomes subjective and time consuming. Hence automation of the segmentation steps using fast, robust and accurate image analysis and pattern classification techniques is necessary for high throughput processing of such datasets. We describe a supervised learning framework, based on artificialneuralnetworks (ANNs), to identify well-segmented nuclei in tissue sections from a multistage watershed segmentation algorithm. The successful automation was demonstrated by screening over 1400 well segmented nuclei from 9 datasets of human breast tissue section images and comparing the results to a previously used stacked classifier based analysis framework.

With more and more attention on the grid current harmonic in recent years, many control schemes of the Pulse Width Modulation Voltage Source Converter (PWM-VSC) have been investigated. Conventional PI controller has shown limitations such as sensitivity to load and system parameter variation. Even the stability of the system can be threatened under a large and sudden load change. In this paper, the practical situation of a VSC for industrial Micro Grid (MG) is considered and an artificialneural network (ANN) based control method is employed to solve the problem. Meanwhile, an on-line parameter tuning algorithm is introduced for its advantage of self-tuning and system character identification. The proposed control scheme is verified through simulation based on SABER software. The simulation results have shown the advantage of the proposed method and the performance of the parameter tuning session.
