The great advance in image processing demands a guarantee for assuring integrity of images. In this paper, a semi-fragile image authentication technique is proposed, which can detect and localize the malicious alteration distinguishing the content-preserving manipulations, such as JPEG compression, from the content alterations. The original image is divided into large blocks (sub-images) that are also divided into 8x8 blocks. Secure image hashing is utilized to generate the sub-image hash (signature) that may slightly change when the content-preserving manipulations are applied. Then, two sub-image hash copies are embedded into relatively-distant sub-images using a doubly linked chain, which prevents the vector quantization (VQ) attack. The hash bits are robustly embedded in chosen discrete cosine transform (DCT) coefficients exploiting a property of DCT coefficients that is invariant before and after JPEG compression. The experimental results show that the proposed technique successfully detects and localizes the content alterations only. Furthermore, It can effectively resist many attacks such as vector quantization attacks.
随着图像处理技术的飞速发展,对图像的完整性提出了更高的要求。本文提出了一种半脆弱图像认证技术,该技术可以检测和定位恶意篡改,并将内容保留操作(如JPEG压缩)与内容篡改区分出来。原始图像被划分为大块(子图像),这些大块也被划分为8x8块。安全图像散列用于生成子图像散列(签名),当应用内容保留操作时,该散列可能会略有变化。然后,使用双链将两个子图像哈希副本嵌入到相对较远的子图像中,从而防止矢量量化(VQ)攻击。哈希位被稳健地嵌入到所选择的离散余弦变换(DCT)系数中,利用了DCT系数在JPEG压缩前后不变的特性。实验结果表明,该方法能够有效地检测和定位图像内容的变化。此外,该算法还能有效抵御矢量量化攻击等多种攻击。

Early Software Fault Prediction Using Real Time Defect Data 利用实时缺陷数据进行早期软件故障预测
Pub Date : 2009-12-28 DOI: 10.1109/ICMV.2009.54
A. Kaur, P. Sandhu, Amanpreet Singh Bra
Quality of a software component can be measured in terms of fault proneness of data. Quality estimations are made using fault proneness data available from previously developed similar type of projects and the training data consisting of software measurements. To predict faulty modules in software data different techniques have been proposed which includes statistical method, machine learning methods, neural network techniques and clustering techniques. The aim of proposed approach is to investigate that whether metrics available in the early lifecycle (i.e. requirement metrics), metrics available in the late lifecycle (i.e. code metrics) and metrics available in the early lifecycle (i.e. requirement metrics) combined with metrics available in the late lifecycle (i.e. code metrics) can be used to identify fault prone modules by using clustering techniques. This approach has been tested with three real time defect datasets of NASA software projects, JM1, PC1 and CM1. Predicting faults early in the software life cycle can be used to improve software process control and achieve high software reliability. The results show that when all the prediction techniques are evaluated, the best prediction model is found to be the fusion of requirement and code metric model.
软件组件的质量可以根据数据的错误倾向来衡量。质量估计是使用从以前开发的类似类型的项目中获得的故障倾向数据和由软件测量组成的训练数据进行的。为了预测软件数据中的故障模块,人们提出了不同的技术,包括统计方法、机器学习方法、神经网络技术和聚类技术。提出的方法的目的是研究是否在早期生命周期中可用的度量(例如需求度量),在后期生命周期中可用的度量(例如代码度量),以及在早期生命周期中可用的度量(例如需求度量)与后期生命周期中可用的度量(例如代码度量)相结合,可以通过使用聚类技术来识别容易出错的模块。该方法已在NASA软件项目JM1、PC1和CM1的三个实时缺陷数据集上进行了测试。在软件生命周期的早期进行故障预测,可以提高软件的过程控制能力,提高软件的可靠性。结果表明,在对所有预测技术进行评估后,发现需求模型和代码度量模型的融合是最好的预测模型。

The current seat adjustment mechanism in automobiles is quite tedious and outdated and has its toll on the body of the person while adjusting the seat to his/her comfortable position. Every person has his/her comfortable seat position, so every time a person sits in an automobile, adjustment of the seat has to be done according to the comfort of the individual, this is tiresome and at times annoying. This paper deals with automating the seat of an automobile through the use of a microcontroller and image processing toolkit of Matlab thereby reducing manual effort in adjusting the seat. The adjustment of the seat can be done horizontally, vertically as well as the inclination of the seat can be changed by controlling the direction of rotation and speed of the motors provided in the seat. The parameters of the comfortable position for different individuals are stored in the database and the seat is adjusted to a person’s comfortable position by using face recognition algorithm which is used to link the parameters of a person’s comfortable position stored in the database to his/her face.
目前的汽车座椅调节机制非常繁琐和过时,并且在调整座椅到自己舒适的位置时对人的身体造成了伤害。每个人都有他/她舒适的座位位置,所以每次一个人坐在汽车里,都必须根据个人的舒适度来调整座位,这是令人厌烦的,有时甚至令人讨厌。本文介绍了利用单片机和Matlab图像处理工具包实现汽车座椅的自动化,从而减少了人工调节座椅的工作量。通过控制阀座内电机的旋转方向和速度,可以调节阀座的水平方向、垂直方向和倾斜方向。将不同个体的舒适体位参数存储在数据库中,并利用人脸识别算法将数据库中存储的人的舒适体位参数与该人的面部相关联,从而将座椅调整到该人的舒适体位。

A Conditional Selection of Orthogonal Legendre/Chebyshev Polynomials as a Novel Fingerprint Orientation Estimation Smoothing Method 条件选择正交Legendre/Chebyshev多项式作为指纹方向估计平滑新方法
Pub Date : 2009-12-28 DOI: 10.1109/ICMV.2009.49

In this paper, a new approach to fingerprint ridge orientation estimation smoothing by a conditional selection of orthogonal polynomials is proposed. This method can smooth the low coherence and consistency areas of fingerprint OF. Also, it is able to estimate the Orientation Field (OF) for fingerprint areas of no ridge information This method does not need any basis information of Singular Points (SPs). The algorithm uses a consecutive application of filtering-based and model-based orientation smoothing methods. A Gaussian filter has been employed for the former. The latter conditionally employs one of the orthogonal polynomials such as Legendre and Chebyshev type I or II, based on the results of the filtering based stage. The experiments have been conducted on the fingerprint images of FVC2000 DB2_A, FVC2004 DB3_A and DB4_A. The results show coarse ridge orientation estimation improvement even in very poor quality images where the orientation information cannot be clearly extracted.
本文提出了一种基于正交多项式条件选择的指纹脊方向估计平滑方法。该方法可以对指纹of的低相干和一致性区域进行平滑处理。对于没有脊信息的指纹区域,该方法不需要任何奇异点的基信息,也能估计出方向场(OF)。该算法使用了基于滤波和基于模型的方向平滑方法的连续应用。前者采用高斯滤波器。后者根据基于滤波的阶段的结果,有条件地使用正交多项式之一,如Legendre和Chebyshev I型或II型。分别对FVC2000 DB2_A、FVC2004 DB3_A和DB4_A的指纹图像进行了实验。结果表明,即使在无法清晰提取方向信息的质量很差的图像中,粗糙的脊方向估计也有改善。

The aim of this paper is to introduce the application of an S-shaped transition curve in designing and generating a spur gear. In engineering field, the spur gear usually designed by using an involute curve where this curve needs to use a tracing point method to obtain a curve while an S-shaped curve can obtain a curve directly. The comparative study between an S-shaped method and direct method in Computer Aided Design (CAD) tool also covered.
