Although it is valuable information that human faces are approximately symmetric, in the literature of facial attributes recognition, little consideration has been given to the relationship between gender, age, ethnicity, etc. and facial asymmetry. In this paper we present a new approach based on bilateral facial asymmetry for gender classification. For that purpose, we propose to first capture the...
Automatic off-line Arabic handwriting recognition based on segmentation still faces big challenges. A database, covering all shapes of handwritten Arabic characters, is required to facilitate the recognition process. This paper introduces a new database for handwritten Arabic characters (HACDB), designed to cover all shapes of Arabic characters including overlapping ones. It contains 6,600 shapes...
Distribution electricity network planning needs consolidated regional and national views of predicted future loads. A power utility established load forecasting tool requires load profile data that will be used in calculating coincidence factors between loads of different classes and sub-classes as per economic activity and geospatial location. Regional industrial and commercial electricity load profile...
Air Force armament maintainers like their beer and they definitely love their beercans. Prior to loading live weapons on an aircraft, maintainers are required to verify that no stray voltage is present and that the firing signals are functioning properly. In the Air Force world, this is done with a small, battery-operated tester called an Armament Circuits Pre-Load Test Set (ACPTS), commonly referred...
It was carried out preliminary study of the effect of degree sample deflected mode on the parameters of the electric response using multisensor control system, based on phenomenon of mechanoelectrical transformations in dielectric structures. Deflected mode provided by the uniaxial compression of the sample in the press. It has been shown the high efficiency of the multisensor system, which allows...
Registration is a very important step in object recognition. Accurate detection of the eye centers, eye corners, mouth and nose are critical for face recognition and more broadly, for face processing. In this work, we have evaluated three techniques, namely AAM, Stacked ASM and CLM, for automatic detection of landmarks under the problem of extremely dense registration scheme for the face. Further...
Traditional image subcategory classification methods combined multiple features into a feature vector. Such methods neglect distinct roles of diverse features on discriminating image subcategories. In this paper, the Dempster-Shafer evidence theory is applied to fuse different features in image subcategory classification. It considers the different contribution of each feature to image classification...
Using image recognition, 20 varieties of peanut are collected through scanner. The image of 100 peanut seeds' positive and two sides of each variety are collected; each image's characteristics of shape, color and texture totaling up to 50 are obtained. A cluster analysis model based on these features and another cluster analysis model with PCA data optimizing is built. For further step, we have got...
The studies of Optical Character Recognition (OCR) are being developed since it still needs a performance improvement. The previous study of alphanumeric character recognition had been conducted by Blumenstein and Liu using Modified Direction Feature (MDF) and Multi Layer Perceptrons (MLP) network. The study reaches the accuracy rate of 70.22% for lowercase characters and 80.83% for uppercase characters.
Shape recognition is an important problem in many applications. A simple string matching approach for shape recognition is proposed in this paper. The shapes are coded as their dominant points. The compactness of polygons formed by the centroid and three consecutive dominant points is used as the feature for recognition. The experimental results showed that the proposed method has better recognition...
Based on spring-mass model, which can effectively represent the mechanical behavior of fabric and simulate its complex deformation, a mathematical model is established using such basic fabric mechanical data as tensile, shear and bending from KES testing system. And then the fabric and skirt static appearance is simulated vividly by computer programming for the mathematical model. The system simulating...
The standard IEC 60060-1:2010 “High-Voltage Test Techniques - Part 1: General definitions and test requirements” defines a parameter called “time to peak”. In addition it describes a method for evaluating the time to peak of switching-impulses. This method suffers from two problems. Firstly, the method is only to be applied to so-called standard switching-impulses. That is impulses essentially equivalent...
In this work we present a discriminative codebook weighting approach for action detection. We learn global and local weights for the codewords by considering the spatio-temporal Hough voting space of the training sequences. In contrast to the Implicit Shape Model (ISM) where all the codewords that are matched to a local descriptor cast votes with uniform weights, we learn local weights for the matched...
We present a very efficient, highly accurate, “Explicit Shape Regression” approach for face alignment. Unlike previous regression-based approaches, we directly learn a vectorial regression function to infer the whole facial shape (a set of facial landmarks) from the image and explicitly minimize the alignment errors over the training data. The inherent shape constraint is naturally encoded into the...
This paper proposes a simple yet effective method to learn the hierarchical object shape model consisting of local contour fragments, which represents a category of shapes in the form of an And-Or tree. This model extends the traditional hierarchical tree structures by introducing the “switch” variables (i.e. the or-nodes) that explicitly specify production rules to capture shape variations. We thus...
This paper presents the result of a recent large-scale subjective study of image retargeting quality on a collection of images generated by several representative image retargeting methods. Owning to many approaches to image retargeting that are developed, there is a need for a diverse independent public database of the retargeted images and the corresponding subjective scores that is freely available...
Typically, oracles used to test graphical user interface(GUI) programs highly depend on environmental factors that are not related to the functionality of the program, such as screen resolution and color schemes. To accommodate these on-functional variations, researchers suggested fuzzy comparison rules that determine whether the output of a GUI program matches the oracles. Others suggested computer...
Monitoring of abnormal activities under video surveillance research area is important due to providing comfort and safety living for the society. The popular scenario is to learn pattern of normal activity, and subsequently detect abnormal events in the scene. Instead of detecting abnormal event, we propose to model the sudden change in the event specifically fall event that deviates from the normal...
Content based image retrieval is an active research issue that had been famous from 1990s till present. The main target of CBIR is to get accurate results with lower computational time. This paper discusses on the comparative method used in color histogram based on two major methods used frequently in CBIR which are; normal color histogram using GLCM, and color histogram using KMeans. A set of 9960...
A textile-based breath-sensing system and the testing results with different postures are described. Two electrodes are placed on a belt, loosely buckled for user comfort, to charge and discharge a capacitor modeled off human movement of breathing. For most conditions of daily activities, the system has demonstrated capable of providing accurate measurement of respiratory rates.
