We address the problem of automatically recognizing artistic movement in digitized paintings. We make the following contributions: Firstly, we introduce a large digitized painting database that contains refined annotations of artistic movement. Secondly, we propose a new system for the automatic categorization that resorts to image descriptions by color structure and novel topographical features as...
This paper describes the design of embedded system that enables the remote access of database by the implementation of web server. Porting of Linux to ARM9 is carried out to enable further porting of embedded webserver (BOA server) and SQLite database. The ported database is implemented by creating a table, storing the data into the database and retrieving the same. An application is developed for...
Sports event recognition and classification is a challenging task due to the number of possible categories. On one hand, how to characterize legitimate event classification names and how to acquire preparing tests for these classes should be investigated, then again, it is non-inconsequential to accomplish acceptable order execution. To address these issues, a content mining pipeline is initially...
The study of the evolution of highly configurable systems requires a thorough understanding of thee core ingredients of such systems: (1) the underlying variability model; (2) the assets that together implement the configurable features; and (3) the mapping from variable features to actual assets. Unfortunately, to date no systematic way to obtain such information at a sufficiently fine grained level...
In this paper, we present landmine detection and discrimination method: one class support vector machine (OSVM) based on RBF kernel using one-dimensional Ground Penetrating Radar (GPR) delivered data. The GPR has been a precious tool for humanitarian demining. It scans the ground and delivers a three-dimensional matrix representing three types of data; Ascan, Bscan and Cscan. The Ascan data represents...
Helitron is considered as very important type of DNA involved in mechanism's evolution. These elements are not well studied and the major researches done are biological experiments. In this paper, we propose a novel approach aiming to characterize and classify helitron's types. Accordingly, we use the Support Vector Machine (SVM) classification technique known to be preferment in DNA related studies...
There have been various measures and techniques which have currently been used in order to measure the similarity between graphs [1]. In this paper, molecules have been represented as graphs with atoms of the molecule being represented as nodes and bonds between atoms being represented as edges [2]. We will first see how various available similarity coefficients perform in order to measure the similarity...
Media streaming is the most rapid-growth network service and occupies most of traffics on Internet. This paper presents approaches for enhancing the network performance for media streaming in two aspects. Firstly, in order to improve the network performance of a media server executing on a Virtual Machine (VM), a network framework using Software-Defined Networking (SDN) is introduced. This framework...
Early diagnosis of stroke is essential for timely prevention and treatment. Investigation shows that measures extracted from various risk parameters carry valuable information for the prediction of stroke. This research work investigates the various physiological parameters that are used as risk factors for the prediction of stroke. Data was collected from International Stroke Trial database and was...
Day to day life is more unsecure as per the hacking is concerned. Our data is not secure because it can be stolen, hacked, destroy, manipulate, password may forget, guess, Card, token, etc. To overcome this problem biometrics is used as a strong authentication system. The person should be present at the time of the instance. Biometric security is challenging task in day to day life because it is difficult...
It has been known that SNPs are the most important types of genetic variations that can influence common diseases and phenotypes. Increasing number of SNP-phenotype related publications, demonstrate the need for an automatic extraction of this association from biomedical articles. Although few corpora have been developed for obtaining the mutation and disease from text, no corpus is available which...
Image quality is a hot topic since most of image analysis and recognition systems are sensitive to degradation. In this paper, we are interested in the quality of document images to recover text content with as few errors as possible. One of the defects that degrades the Optical Character Recognition rate (OCR) is blur. Therefore, we propose to detect blur and to attenuate its effect on an OCR result...
Categorical description of leaf shapes is of paramount importance in agriculture and plant sciences. Traditionally, these descriptions have been based on categorical systems proposed by domain experts. Despite the importance of these visual descriptive systems, these approaches may be limited by the representation of unknown shapes as expected in exploratory domains. In this work, we propose a novel...
GAT (Global Affine Transformation) and GPT (Global Projection Transformation) correlation matchings were successively proposed by Wakahara and Yamashita which use affine transformation (AT) and 2D projection transformation (PT), respectively, to maximize the normalized cross-correlation value between a template and a GAT/GPT-superimposed input image. In theory, to maximize the degree of matching via...
This paper proposes a speech/music classification system based on i-vector. An analysis of two classification methods, namely cosine distance score (CDS) and support vector machine (SVM) is performed. Two session compensation methods, within-class covariance normalization (WCCN) and linear discriminant analysis (LDA) are also discussed. The performance of proposed systems yields better results compared...
Face recognition is a quintessential biometric technique. It still remains challenging to accurately characterize the identity related features in face images. In this paper, we propose a novel classification method based on Kernel Fisher Discriminant Analysis using the distinctiveness of Gabor features and the robustness of ordinal measures. These parameters are derived from magnitude, phase, real...
With recent advances in deep convolutional neural networks (CNN), deep learning has brought significant quality improvement and flexibility on single image super resolution (SR). In this paper, we describe how CNN based SR can be accelerated on integrated GPUs. To this end, we employ a CNN model from an existing single image SR approach, and develop the model within a well-known deep learning framework...
This paper proposed a novel blind image quality assessment method that is created by training a convolutional neural network to learn discriminant features of image quality and fitting the features with a support vector regression to get an evaluation score. The pooling procedure is help to reduce the feature dimension and improve computation efficiency. The proposed method does not need any hand-crafted...
In this paper, we introduce algorithms for pruning and aging user ratings in collaborative filtering systems, based on their oldness, under the rationale that aged user ratings may not accurately reflect the current state of users regarding their preferences. The aging algorithm reduces the importance of aged ratings, while the pruning algorithm removes them from the database. The algorithms are evaluated...
As secure processing as well as correct recovery of data getting more important, digital forensics gain more value each day. This paper investigates the digital forensics tools available on the market and analyzes each tool based on the database perspective. We present a survey of digital forensics tools that are either focused on data extraction from databases or assist in the process of database...
