background the first commercial system for digital radiography was introduced in 1987, and it has evolved a great deal since then. currently, it is possible to enhance images in digital radiography. objectives the aim of this study is to evaluate the diagnostic accuracy of image enhancement in direct digital radiography as it relates to interproximal carries assessment. conclusions using these ...

Grassland vegetation can provide visual cover for terrestrial vertebrates. The most commonly used method to assess visual cover is the Robel pole. We test the use of digital photography as a more accurate and repeatable method. We assessed the digital photography method on four forage grassland species (Pseudoroegneria spicata, Festuca campestris, Poa pratensis, Achnatherum richardsonii). Digit...

In volcanic areas, where it can be difficult to perform direct surveys, digital photogrammetry techniques are rarely adopted for routine volcano monitoring. Nevertheless, they have remarkable potentialities for observing active volcanic features (e.g., fissures, lava flows) and the connected deformation processes. The ability to obtain accurate quantitative data of definite accuracy in short ti...

Our study provides insight into modelling and assessment of a digital surface model of experimental plot. An unmanned aerial vehicle equipped with low-cost RGB camera was used. The camera system made it possible to acquire very high resolution imagery to generate ortho-mosaics and digital surface models through automatic 3D photo-reconstruction methods by Agisoft Photoscan solution. The unmanne...

Digital photo album softwares like iPhoto have enjoyed great popularity for years. These years, online photo album services (e.g., Flickr and Picasa) have been becoming more and more popular with the development of social Web. In this paper, we demonstrate our effort called TuneSensor to recommend music for photo albums automatically. In particular, we exploit semantic data to represent both im...

Due to the proliferation of social media platforms, digital photo sharing has emerged as a new way of establishing chronology of events and reminiscing forgotten experiences. The growing trend of presenting visual content using timelines or shared photo streams offers new possibilities to social media applications. In this paper, a novel interface for visualisation and sharing of multiple photo...

Digital photos are massively produced while digital cameras are becoming popular, however, not every photo has good quality. Blur is one of the conventional image quality degradation which is caused by various factors. In this paper, we propose a scheme to detect blurred images and classify them into several different categories. The blur detector uses support vector machines to estimate the bl...

gully erosion is one of the most severe types of water erosion that inclusive and global model to represent its development under different environmental circumstances is difficult. moreover, having knowledge about history behaviors of a gully and its advancement requires direct annual monitoring that is not possible in iran conditions because of cost and time. gis and remote sensing with provi...

Annotation process is important because it has a direct impact in the way in which photo retrieval is performed in locating the photos from the photo database. However, users want an efficient approach to access or retrieve photos based on metadata of images. So, annotation process would be vital and operational going to archive high user performance in photo retrieval process. In this paper we...

background: early and non-invasive determination of blood glucose level is of great importance. we aimed to present a new technique to accurately infer the blood glucose concentration in peripheral blood flow using non-invasive optical monitoring system. methods: the data for the research were obtained from 900 individuals. of them, 750 people had diabetes mellitus (dm). the system was designed...
