A-CCNN: adaptive ccnn for density estimation and crowd counting
ICIP 2018/ IEEE
Crowd counting, for estimating the number of people in a crowd using vision-based computer techniques, has attracted much interest in the research community. Although many attempts have been reported, real-world problems, such as huge variation in subjects' sizes in images and serious occlusion among people, make it still a challenging problem. In this paper, we propose an Adaptive Counting Convolutional Neural Network (A-CCNN) and consider the scale variation of objects in a frame adaptively…
Crowd counting, for estimating the number of people in a crowd using vision-based computer techniques, has attracted much interest in the research community. Although many attempts have been reported, real-world problems, such as huge variation in subjects' sizes in images and serious occlusion among people, make it still a challenging problem. In this paper, we propose an Adaptive Counting Convolutional Neural Network (A-CCNN) and consider the scale variation of objects in a frame adaptively so as to improve the accuracy of counting. Our method takes advantages of contextual information to provide more accurate and adaptive density maps and crowd counting in a scene. Extensively experimental evaluation is conducted using different benchmark datasets for object-counting and shows that the proposed approach is effective and outperforms state-of-the-art approaches.

Structured Inhomogeneous Density Map Learning for Crowd Counting
arXiv preprint arXiv:1801.06642
In this paper, we aim at tackling the problem of crowd counting in extremely high-density scenes, which contain hundreds, or even thousands of people. We begin by a comprehensive analysis of the most widely used density map-based methods, and demonstrate how easily existing methods are affected by the inhomogeneous density distribution problem, e.g., causing them to be sensitive to outliers, or be hard to optimized. We then present an extremely simple solution to the inhomogeneous density…
In this paper, we aim at tackling the problem of crowd counting in extremely high-density scenes, which contain hundreds, or even thousands of people. We begin by a comprehensive analysis of the most widely used density map-based methods, and demonstrate how easily existing methods are affected by the inhomogeneous density distribution problem, e.g., causing them to be sensitive to outliers, or be hard to optimized. We then present an extremely simple solution to the inhomogeneous density distribution problem, which can be intuitively summarized as extending the density map from 2D to 3D, with the extra dimension implicitly indicating the density level. Such a solution can be implemented by a single Density-Aware Network, which is not only easy to train, but also can achieve the state-of-art performance on various challenging datasets.

A new multi-objective cluster ensemble based on modularity maximization
Journal of Engineering Research (JER)
Conventional clustering algorithms utilize only one single criterion that may not conform to diverse shapes of the underlying clusters. But in this paper, we hire two important criteria and propose a new multi-objective cluster ensemble model to empower finding clusters of different types. The first criteria are the well-known sum of squared error. The second criterion is modularity which is originally a measure of evaluating communities in social networks. We maximize modularity as a consensus…
Conventional clustering algorithms utilize only one single criterion that may not conform to diverse shapes of the underlying clusters. But in this paper, we hire two important criteria and propose a new multi-objective cluster ensemble model to empower finding clusters of different types. The first criteria are the well-known sum of squared error. The second criterion is modularity which is originally a measure of evaluating communities in social networks. We maximize modularity as a consensus function of cluster ensemble. In order to further improvement, we also modify Non Dominant Sorting Genetic Algorithm (NSGAII) and propose a specialized crossover operator for it. Experimental results over seven UCI real data sets show that the proposed method significantly outperforms other clustering methods.

Availability challenge of cloud system under DDOS attack
Indian Journal of Science and Technology
Abstract Cloud computing is a distributed architecture that has shared resources, software,
and information is provided to computers and other devices on a scalable platform and
demand. Availability of the cloud services is one of the key security issues in it. Distributed
Denial of Service (DDoS) is an attack that threats the availability of the cloud services. In this
paper, effect of the DDoS attack on the cloud is investigated. Therefore, a model for attack

A new robust digital image watermarking technique based on joint DWT-DCT transformation
Third International Conference on Convergence and Hybrid Information Technology, 2008. ICCIT'08.
Abstract In this paper, a new robust digital image watermarking algorithm based on Joint
DWT-DCT Transformation is proposed. The imperceptibility is provided as well as higher
robustness against common signal processing attacks. A binary watermarked image is
embedded in certain sub-bands of a 3-level DWT transformed of a host image. Then, DCT
transform of each selected DWT sub-band is computed and the PN-sequences of the
watermark bits are embedded in the coefficients of…

Effect of Locations of Using High Boost Filtering on the Watermark Recovery in Spatial Domain Watermarking
Indian Journal of Science & Technology
Abstract Generally, High Boost filter is used to emphasize high frequency components
representing the image details without eliminating low frequency components representing
the basic form of the signal. The dissimilarity between the watermark and unwatermarked
parts of the image are increased by this filter. Thus, watermark could be recovered
significantly better by recovery algorithm. In this paper, a comparison is taken place between
the effects of different places of…
