  • Biometrics: Iris Recognition

    1128 Words  | 3 Pages

    Iris recognition is one of commonly employed biometric for personal recognition. In this paper, Single Value Decomposition (SVD), Principal Component Analysis (PCA), Automatic Feature Extraction (AFE) and Independent Component Analysis (ICA) are employed to extract the iris feature from a pattern named IrisPattern based on the iris image. The IrisPatterns are classified using a Feedforward Backpropagation Neural Network (BPNN) and Support Vector Machines (SVM) with Radial Basis Function (RBF) kernel

  • Improve ATM Security by Face Recognition

    1369 Words  | 3 Pages

    Abstract- In this paper the method face Recognition is using to access Automated teller machines (ATMs). ATMs are used to do banking function like checking balance withdraw money, changing pin numbers etc. The ATM cards and pin numbers are used for security purpose. But this system is using SIM card in place of ATM cards. In order to improve security the system first authenticate the person if he/she is recognized then it will ask the password of the account. This system used Spartan 3 FPGA board

    variable is considered as an individual dimension. Standard Deviation: Standard Deviation is a measure about how spreads the numbers are. It describes the dispersion of a data set from its mean. If the dispersion of the data set is higher from the mean value, then the deviation is also higher. It is expressed as the Greek letter Sigma (σ). ... ... middle of paper ... ...ferred because it produces meaningful information about each data point and where it falls within its normal distribution, plus provides

  • Steep Slope Analysis

    706 Words  | 2 Pages

    Interpretation The graph 1shows the extraction of the components on the steep slope. The first 5 components are the part of steep slop. The components on the shallow slope contribute little to the solution. The components nine to nineteen are the part of shallow slop. The big drop occurs between the sixth and ninth components, so first 5 components are used for further analysis. The scree plot confirms the choice of six components. Table 5 Component Matrixa Component 1 2 3 4 5 6 7 8 9 Hours

    its value in the vector is a non-zero value. Several different ways of computing the term weights have been developed, one of which is the frequency-inverse document frequency (tf-idf) weights. The frequency portion if td-idf refers to the frequency of the term within the document. The inverse document frequency is the log function of the total number of documents / divided by the number of documents in which the term appears.The frequency-inverse document model just multiplies these 2 values.

    and/or behavioral characteristics. A palm print refers to an image acquired of the palm region of the hand. The biometric use of palm prints uses ridge patterns to identify an individual. It is rich in its features: principal lines, wrinkles, ridges, singular points and minutiae points.[1] Palmprint recognition is a complex task because the palmprints vary highly in terms of quality, size, shape, rotation and occlusion.[5] Biometric performance evaluation is an important task, particularly for palmprint

  • Women In Love Theme

    Ursula and Gudriun are told, various other main characters are introduced. Along with Ursula and Gudrun Brangwen, Rupert Birkin and Gerald Crich are both central characters in Women in Love. Containing innumerable sub-themes, Women in Love holds a singular theme to which all others may be tied: sexuality. Opposed to employing subtleties, D.H. Lawrence opts for uninhibited writing when defining the sexuality of his characters. There are a variety of methods by which Lawrence is able to achieve a novel

  • Digital Watermarking Essay

    understand this feature is to embed a level of the authentication signature into the digital image using a digital watermark. In the case of the image being tampered, it can easily be detected as the pixel values of the embedded data would change and do not match with the original pixel values. There are many spatial and frequency domain techniques are available for authentication of watermarking. Watermarking techniques are judged on the basis of their performance on... ... middle of paper ..

  • Collaborative Tagging Essay

    2334 Words  | 5 Pages

    Abstract Collaborative tagging describes the process by which many users add metadata (tags) in the form of keywords to share content. The main purpose of tagging is to categorize the web resources based on their content. The collaborative tagging services has grown in popularity on the web leads to cross referencing, thereby recognizing the privacy threat. In this paper, we proposed privacy-enhancing technology called tag suppression, used to protect end-users privacy. Index Terms— Policy-based

  • Postmodernism

    3924 Words  | 8 Pages

    Postmodernism Traditional thinking has understood the world in its totality as including both chaos and harmony. Lovelock's hypothesis gives us a new resolution to this problem by expanding or even relocating creativity from the human intellect to the world. Postmodernism is the return to the mythological-aesthetic reflexion of the world concerning the idea of order and harmony. Facing the publicly known and proclamated appeals for further prosperity, scepticism is being survived so deeply

  • Recent Trends in Document Clustering with Evolutionary-Based Algorithms

    742 Words  | 2 Pages

    Document clustering is the process of organizing a particular electronic corpus of documents into subgroups of similar text features. Previously, a number of statistical algorithms had been applied to perform clustering to the data including the text documents. There are recent endeavors to enhance the performance of the clustering with the optimization based algorithms such as the evolutionary algorithms. Thus, document clustering with evolutionary algorithms became an emerging topic that gained

    marvelously by greedily exploiting their employees, unfortunate people who toiled long hours in grimy factories to barely earn their subsistence. Utilitarianism was a prevalent viewpoint during this period of industrial frenzy, for it embraced the values of practicality and efficiency; and the success and survival of the participants of industrial society often depended on these standards. Dickens was disgusted with the single-mindedness of his society and with the dreary, inanimate atmosphere that
