Development of Automatic Crack Identification Algorithm for a Concrete Sleeper Using Pattern Recognition

Concrete Crack Identification Using a UAV Incorporating Hybrid Image Processing

Crack assessment is an essential process in the maintenance of concrete structures. In general, concrete cracks are inspected by manual visual observation of the surface, which is intrinsically subjective as it depends on the experience of inspectors. Further, it is time-consuming, expensive, and often unsafe when inaccessible structural members are to be assessed. Unmanned aerial vehicle (UAV)...

Automatic review identification on the web using pattern recognition

In this paper we propose the ARROW (Automatic Review Recognition and annOtation of Webpages) method which is capable of identifying and annotating user submitted reviews on a Web page. The method consists of six steps: data preparation, page-level pattern identification, subjectivity analysis, container structure analysis, review properties identification, and review annotation. For the evaluat...

development of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles

a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...

Statistical Pattern Recognition for Automatic Writer Identification and Verification

This chapter evaluates the performance of edge-based directional probability distributions as features in writer identification in comparison to a number of other texture-level features encoding non-angular information. We introduce here a new feature: the joint probability distribution of the angle combination of two ”hinged” edge fragments. It is noted that the ”edge-hinge” distribution outpe...
