  • MPEG-7 will define a certain set of descriptors to describe these features. For example, the color histogram can be a very suitable descriptor for color characteristics of an image, and motion vectors (commonly available in compressed video bitstreams) form a useful descriptor for motion characteristics of a video clip. MPEG-7 also uses the concept of description scheme (DS), which means a framework that defines the descriptors and their relationships. Hence, the descriptors are the basis of a description scheme. Description then implies an instantiation of a description scheme.

  • In various applications, we often haveto deal with sets of images of a certain type; for example,X-rayimages, traffic sceneimages,etc.Eachimage in the set may be different from all the others, but at the same time all images may share certain common characteristics. We need the statistical description of images so that we capture these common characteristics and use them in order to represent an image with fewer bits and reconstruct it with the minimum error “on average”.

  • An effective separation method of very pure binder fraction to assess radiocarbon dating is proposed in the present contribution. The elimination of contaminant error sources and the suitable selection of mortar samples enable the reliable dating. Petrographic analysis under polarizing light microscopy is used to identify different mineralogical phases of mortar samples, aggregate nature, and the limestone fragment remains.

  • Plants are a distinct kingdom of organisms that possess unique properties of reproduction, development, physiology, and adaptation. Plant diversity refers to the variety of plants that exist on the Earth. Plants, in order to survive, have to compete with other plants and organisms in an ecosystem. Over time, they have developed various characteristics to help them survive, which leads to plant diversity.

  • Dyspnea is the subjective sensation of uncomfortable or difficult breathing. Most patients report dyspnea as "shortness of breath." Patients report dyspnea when their breathing is excessive for the activity that they are doing. The sensation of dyspnea is produced by stimulation of both central and peripheral receptors that monitor respiratory muscle activity, hypoxia, hypercapnia, acid-base status, airway irritation, and changes in the pressure volume characteristics of the lung (i.e., j receptors in lung fibrosis or emphysema).

  • The Particle Image Velocimetry is undoubtedly one of the most important technique in Fluid-dynamics since it has a spatial character that allows to obtain a direct and instantaneous visualization of the flow field in a non-intrusive way. It represents the point of arrival of an intense research on the laser techniques and its origin dates back at the beginning of 80’s when Meynart, a doctoral student of the Von Karman Institute, while explorying the Laser Speckle Velocimetry technique, guessed the importance of capturing the movements of individual particles instead of speckles.

  • When consumers buy products like for instance food products, they make choices by comparing price and quality among alternatives|e.g. a standard product and an animal-welfare oriented variant. The choice between product variants is influenced by the available information channels and the related uncertainty of information concerning di erent quality characteristics.

  • Noninvasive cardiac imaging is an integral part of the practice of current clinical cardiology. During the past three decades a number of distinctly different noninvasive imaging techniques of the heart, such as radionuclide imaging, echocardiography, magnetic resonance imaging, and X-ray computed tomography have been developed. Remarkable progress has been made by each of these technologies in terms of technical advances, clinical procedures, and clinical applications/indications.

  • The use of fluid microdrops in engineering and experimental science goes back over a century to the study and use of spray generated aerosols, and the use of aerosol produced microdrops to confirm the predictions of fluid mechanics, atomic theory and chemistry. The ability to generate fluid microdrops with a predetermined size, on demand, with precisely controlled trajectories is a more recent invention dating back only a few decades. Its primary commercial and industrial use today is in the field of inkjet image printing....

  • At this writing the Cassini spacecraft has fired its engine and successfully inserted itself and its precious cargo of scientific instruments into orbit, the first step of its exploration of the Saturnian system. The suspense is not over, however. While exciting images of the rings have been captured, an exotic composition of Phoebe sensed by the mapping spectrometer and unexpected panoply of magnetic waves and plasma dynamics encountered on the incoming trajectory and initial orbit, the Huygens probe is still on board and the first close flyby of Titan has not taken place....

  • The demand of transmission of images and video is increasing quickly recently and researchers are trying to invest good solutions to improve the quality of these over wireless networks. There are still challenges due to the different characteristics and quality of images between wired and wireless channels. An important issue is congestion control to ensure network stability and achieve a reasonably fair distribution of the network resources among the users.

  • The extreme price volatility of recent years may continue, as many of the factors that caused recent price swings remain in flux. FAPRI-MU recognizes this uncertainty and considers 500 alternative outcomes for the future based on different assumptions about the weather, the price of petroleum and other factors that will affect the supply and demand for agricultural commodities. The tables which follow generally report the averages of the 500 alternative outcomes, but it is important to recognize that actual market results may vary greatly from the reported averages.

  • We studied theoretically and experimentally the transformation, attenuation, and setup due to shoaling and breaking of internal waves in a two-layer fluid system on a uniform slope. An image processing technique was used to illustrate 2D instantaneous displacements of density interface. These results were compared with the calculated values by using the method of characteristics, the simple shoaling model with energy dissipation, and the momentum balance equation based on a radiation stress concept.
