The performance of a biometric system gets affected by various types of errors such as systematic errors, random errors, etc. These kinds of errors usually occur due to the natural variations in the biometric traits of subjects, different testing, and comparison methodologies. Neither of these errors can be easily quantifiable by mathematical formulas. This behavior introduces an uncertainty in the...
Traditional methods of testing were based on Instrument-Centric models which included sensor and measurement capabilities inside of instruments that allowed test engineers to be able to perform measurements and collect data. Such data would then be analyzed by software to determine whether the test resulted in a pass or fail disposition. Modern technologies have significantly changed the equation...
This paper presents the new face verification algorithm based on deep convolutional neural network. The algorithm produces face feature vectors, distance between these vectors allows to determine whether images from the same class. Comparative experimental results are given for LFW test database and modern face recognition algorithms. ROC-curve and equal error rate are used to determine the accuracy...
The article considers the architecture of an information system for automating the testing of user interfaces based on the use of Internet technologies. The general description of the system operation, the description of the main modules, the structure of the interface of the Internet resource are given.
This paper presents a series of experiments on the classification of emergency phone conversation records using artificial neural networks (ANNs). Input data which were processed by ANNs were the features of callers and events taken from emergency phone calls. The authors analyzed four variants of classification: the groups of callers which have specified features, the groups of events which have...
The emotional database can be classified as spontaneous and simulated emotions. Spontaneous emotions can be identified based on the two parameters 1) Arousal and 2) Valence values represented in a two dimensional plane. Arousal measures how calming or exciting the information is, whereas valence measures postive or negative affectivity of information. The objective of the paper is to predict the arousal...
In this paper, a hybrid broadcast broadband TV (HbbTV) test system with the automatic testing subsystem is proposed. The proposed system is based on Node.js framework with SQLite database on the backend side and Polymer framework on the front-end side. The paper covers basic testing metodology and design process with the emphasis on the implementation and testing.
This letter presents a prototype discriminative learning (PDL) method for image set classification. We aim to simultaneously learn prototypes and a linear discriminative projection to drive that in the target subspace each image set can be discriminated with its nearest neighbor prototype. To reveal the unseen appearance variations implicitly in an image set, the prototypes are actually “virtual,”...
Facial recognition is a challenging problem in image processing and machine learning areas. Since widespread applications of facial recognition make it a valuable research topic, this work tries to develop some new facial recognition systems that have both high recognition accuracy and fast running speed. Efforts are made to design facial recognition systems by combining different algorithms. Comparisons...
Outlier detection is a primary step in many data mining applications. An outlier is an abnormal individual from a population, which usually leads poor accuracy in models. Medical literatures are the most reliable resources for researchers to know the progress in their research areas and latest contributions from others. Traditional keyword search retrieves all the text data that contain the keywords...
The number of deaths due to the motor vehicle accidents has increased drastically during the last few years. It is estimated that nearly 40–50 % of the accidents are due to the distractions of the driver. One of the methods to assess driver distraction is using head pose estimation. The unavailability of a standard driving database hampers the study and testing of driver distraction algorithms. In...
Hadith is the second source of Islamic law after Qur'an and an explanation of verses of the Qur'an. Today, there are many hadiths that appear and that are doubtful of its authenticity. The number of hadits that are doubtful of its authenticity or so-called dhaif and maudhu hadith can lead to errors in the determination of Islamic law for everyday life. The classification of hadith is required to know...
Security concerns increase as the technology for falsification advances and biometrics provides airtight security by identifying an individual based on the physiological and/or behavioral characteristics. Physiological hidden biometrics represented by ECG biomedical signal is highly confidential, sensitive, and hard to steal and replicate, and also hold great promise to provide a more secure biometric...
Fraud, waste, and abuse in medical insurance contributes to significant increases in costs for providers and patients. One way to reduce costs is through the detection of abnormal medical practices that could indicate possible fraud. In this paper, we expand upon our previous research into medical specialty anomaly detection by validating the efficacy of our model using real-world fraud cases, and...
Case-Based Reasoning also known as CBR model has been widely used to solve the problem in various cases. This study aims to explain the implementation of K-Nearest Neighbor Algorithm in Case-Based Reasoning model. The research showed that KNN algorithm is suitable to be used in CBR model. The results of this study are to measure the accuracy level of automatic answer identity formation and search...
In the animation movie production, there is a common tool namely motion capture (mocap) to capture the motion of actors. Using this technology, reconstruction of actors motion is being mapped to drive 3D character in the animation. In the reconstruction process of human motion, there were some significant parameters that affect the quality of the result such as subtle motion and high precision reconstruction...
Previous fingerprinting techniques proposed for sensor-based indoor localization assume that the fingerprint database is constructed by the measurement of received signal strength (RSS) at a fixed transmit power of the transmitter sensors. In order to improve the performance of the fingerprinting technique, we consider using the measurement of path loss rather than RSS to better distinguish the signal...
Synthetic Aperture Radar (SAR) image land cover classification is an important task in SAR image interpretation. Supervised learning, such as Convolutional Neural Network (CNN), demands instances which are accurately labeled. However, a large amount of accurately labeled SAR images are difficult to produce. In this paper, a Probability Transition CNN (PTCNN) is proposed for patch-level SAR image land...
Palm vein recognition is developing biometric identification technology. It can be used in physical security and information security for selective control of access to a place or resource. A palm vein recognition has been gaining research interest from last few years because it use physiological intrinsic that uniqueness, stability, not easily spoofed and damaged and have live body identification...
The aim of this research is to design an implementation of the speech recognition system to control the speed of a DC motor. The Linear Predictive Coding (LPC) method is used in the speed recognition system, tuned by the Adaptive Neuro-Fuzzy Inference Systems (ANFIS) method. There are 5 (five) samples of voice signals in Bahasa Indonesia recognized by this system, i.e.: “Nyala”, “Lambat”, “Sedang”,...
