Taschenbuch. Zustand: Neu. Neuware -In this book an in-depth study of the state-of-art illumination invariant face recognition techniques have been carried out and a method based on the fusion of two different feature extraction techniques is proposed to overcome the adverse illumination conditions. The proposed system uses the gradient based illumination normalization to remove the illuminance component superiority. To obtain the illumination insensitive face representation, a ratio of the gradient amplitude to the original image intensity is obtained. The facial features are extracted using two different feature extraction techniques. Local binary pattern (LBP) is a very efficient local texture descriptor based on thresholding the pixels in a small neighborhood based on the value of the center pixel. Local ternary pattern (LTP) is a noise resistant modified version of LBP. The features vectors provided by the two techniques are fused at feature level. Finally artificial neural network is used in the classification stage for recognition purpose.Books on Demand GmbH, Überseering 33, 22297 Hamburg 88 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Natural immune system offers several fascinating options that motivated the planning of Artificial Immune Systems (AIS) accustomed solve varied issues of engineering and Artificial Intelligence (AI). AIS are significantly thriving in fault detection and diagnosing applications where anomalies like errors and failures are assimilated to viruses that ought to be detected. Thereby, AIS appear appropriate to automatically discover forgeries in signature verification systems. This work proposes a technique for offline signature verification that's supports the artificial Immune Recognition System (AIRS) and Artificial Neural Network (ANN) utilized in verification stage. For feature generation, two totally different descriptors are projected to get signature traits. the primary is that the Gaussian pyramid used for texture synthesis that is very redundant, coarse scales offer a lot of the data within the finer scales and Laplacian pyramid Seamlessly stitch along images into an image plaid (i.e., register the photographs and blurring the boundary), by smoothing the boundary in a very scale-dependent style to avoid boundary artefacts.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -This work is motivated by the potential and promise of image fusion technologies in the multi-sensor image fusion system. The aim of this research is to focus on multi-sensor pixel level image fusion for medical application due to its significance of medical field. Medical fusion methods are only a possible way that able to combine correlating information of multiple images into a single image to explore the possibility of data reduction and improvement of information density. The dissertation explores the possibility of using Stationary Wavelet approach in image fusion and further optimization using Genetic Algorithm and Particle Swarm Optimization. The comparative analysis of Stationary wavelet transform combined with optimization algorithm has been performed with several sets of computed Tomography (CT) scan and Magnetic Resonance imaging (MRI) images using MATLAB. Improve statistics results are obtained in terms of peak signal to noise ratio (PSNR), entropy, root mean square error (RMSE), edge strength, mutual information.Books on Demand GmbH, Überseering 33, 22297 Hamburg 88 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -In this work, technique is proposed to identify dust particles from the camera image. The dust particles on the image are the small noise on the image which is raised when the picture is clicked and at that time dust is there on the lens of camera. In the previous work, salient based bottom up method is applied which will analyze various pixels of the image. The bottom up method will generate salient object on the basis of similarity of the pixels in the image. The pixels which are similar have one matrix and pixels which have dissimilarity have different matrices. To improve accuracy of dust particle detection, ITTI-KOCH algorithm is used in the proposed work. In the algorithm, saliency is designed in which properties of the image is analyzed and pixels which have dissimilarity are put into different matrices and that matrices pixels are marked as noise in the image.Books on Demand GmbH, Überseering 33, 22297 Hamburg 80 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -In this book, a segmentation method for automatic detection and extraction of brain tumor from Magnetic Resonance Imaging (MRI) images using fuzzy c-means (FCM) clustering and seeded region growth is being presented. The MRI technique provides an excellent contrast between the brain tissues and the tumour tissues. The area containing the tumour is brighter in intensity than the area of healthy brain tissues. The image processing techniques and algorithms are applied on the MRI images of the brain tumour. These images are provided as input to the MATLAB software and pre-processing operations viz., image resizing and conversion to grayscale are applied on this input image. The image is then enhanced using the two-dimensional wavelet decomposition in such a way that the finer details in the image are improved. After the enhancement operation, fuzzy c-means clustering (FCM) is applied for segmentation, which divides the image into a number of clusters, on the basis of intensity values of the pixels.Books on Demand GmbH, Überseering 33, 22297 Hamburg 88 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Image fusion is a technique that integrate complimentary details from multiple input images such that the new image give more information and more suitable for the purpose of human visual perception. Nearly all block-based transform schemes for image and video coding developed so far choose the 2-D discrete cosine transform (DCT) of a square block shape. With almost no exception, this conventional DCT is implemented separately through two 1-D transforms, one along the vertical direction and another along the horizontal direction. We develop a new block-based DCT framework in which the first transform may choose to follow a direction other than the vertical or horizontal one. The coefficients produced by all directional transforms in the first step are arranged appropriately so that the second transform can be applied to the coefficients that are best aligned with each other. Compared with the conventional DCT, the resulting directional DCT framework is able to provide a better coding performance for image blocks that contain directional edges-a popular scenario in many image signals.Books on Demand GmbH, Überseering 33, 22297 Hamburg 60 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Image processing and analysis algorithms are widely used in medical systems to analyze medical images for diagnose the disease of a patient. This book covers one of the demanding problems of a medical system: Stitching of X-ray Images. The flat panel of an X-ray system cannot cover all parts of a body, So Image stitching is incorporated in the medical system to combine two or more X-ray images and get a single high resolution image. Image Stitching is a process of basically combining two or more images to form a panoramic image. Stitching includes two main parts: Image matching and Image blending. For Image Matching two algorithms are used SIFT and SURF. SIFT is more effective algorithm for scale and rotational image stitching but it cannot cope with illumination variation whereas SURF method provides better computation speed and it has the distinctive property of illumination invariance. So if responses from SIFT and SURF based algorithm combines they regenerates a panoramic image having the best features of both the algorithm.Books on Demand GmbH, Überseering 33, 22297 Hamburg 68 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -A biometric system is basically a pattern recognition system being employed in averse circumstances. Since, biometric system like any traditional security system is revealed to mischievous adversaries, which can contrive data to make the system abortive by implicating its integrity. Current theory and design methods of biometric systems do not consider vulnerability to such adversary attacks. Therefore, analysis of classical design approaches is an open issue to inquire whether they precede to contrive secure systems. In order to build, secure biometric systems it is requisite to comprehend and investigate the threats and thus to enroot the adequate counter measures and robust systems designs, both methodologically and strategically, if required. Consequently, the accession of theory and design methods of biometric systems is compulsory to convoy the security and credibility of biometric systems in adversarial circumstances.Books on Demand GmbH, Überseering 33, 22297 Hamburg 100 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -The authentication for access control includes token-based identification or knowledge based identification. In token based method person should possess driving license, passport or and any other authorized identification (ID) card. In knowledge-based identification systems passwords or unique codes are used. Both these authentication methods are not safe because passport or licenses can be stolen and passwords can be hacked. So a unique and secure system is needed. Every individual possess unique biological characteristics and biometrics is related to these measureable biological traits. These are iris, fingerprint, hand, voice, palm geometry recognition and face recognition. Out of all these traits face recognition is the only trait which does not involve the active presence of a person. So these days face is the prime focus of attention. Human brain is quite intelligent to recognize faces under different conditions. But for computer system it is a difficult task. Face recognition is of two types: appearance based and feature based. In appearance based face recognition method holistic features are applied to whole face or sub regions in a face.Books on Demand GmbH, Überseering 33, 22297 Hamburg 156 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Un sistema biométrico es básicamente un sistema de reconocimiento de patrones que se emplea en circunstancias adversas. Puesto que, el sistema biométrico, como cualquier sistema de seguridad tradicional, está expuesto a adversarios malintencionados, que pueden maquinar datos para hacer abortar el sistema implicando su integridad. La teoría y los métodos de diseño actuales de los sistemas biométricos no tienen en cuenta la vulnerabilidad a estos ataques de los adversarios. Por lo tanto, el análisis de los enfoques de diseño clásicos es una cuestión abierta para investigar si preceden a la creación de sistemas seguros. Para construir sistemas biométricos seguros es necesario comprender e investigar las amenazas y, por lo tanto, establecer las contramedidas adecuadas y los diseños de sistemas robustos, tanto metodológica como estratégicamente, si es necesario. En consecuencia, la adhesión a la teoría y a los métodos de diseño de los sistemas biométricos es obligatoria para convoyar la seguridad y la credibilidad de los sistemas biométricos en circunstancias adversas.Books on Demand GmbH, Überseering 33, 22297 Hamburg 88 pp. Spanisch.

Comme tout système de sécurité traditionnel, les systèmes biométriques sont exposés à des adversaires malveillants, qui peuvent manipuler des données pour rendre le système inopérant en mettant en cause son intégrité. La théorie et les méthodes de conception actuelles des systèmes biométriques ne tiennent pas compte de la vulnérabilité à ces attaques adverses. Par conséquent, l'analyse des approches classiques de conception est une question ouverte pour savoir si elles permettent de créer des systèmes sûrs.
