Imaging, description

Recognition Recognition of objects in an image by comparing image descriptions with object models. 

Section XIII deals with image description, with an emphasis on the problem of recognizing objects in an image. It reviews properties and relations, relational stmctures, models, and knowledge-based image analysis. 

Images are usually described as being composed of parts (regions, objects, etc.) that have certain properties and that are related in certain ways. Thus an important step in the process of image description is segmentation, that is, the extraction of parts that are expected to be relevant to the desired description. This section reviews a variety of image segmentation techniques.

Unlike most words in a glossary of tenns associated with the theoretical description of molecules, the word synnnetry has a meaning in every-day life. Many objects look exactly like their mirror image, and we say that they are syimnetrical or, more precisely, that they have reflection synnnetry. In addition to having reflection synnnetry, a pencil (for example) is such that if we rotate it tln-ough any angle about its long axis it... 

The classical description of magnetic resonance suffices for understanding the most important concepts of magnetic resonance imaging. The description is based upon the Bloch equation, which, in the absence of relaxation, may be written as... 

The denomination of odors was schematically related to two separate domains, both related to the memory stimulus of an event concomitant with the perception of the odor. One domain was based on an actual reference point that contains the odor vectors the other was associated with an odor stimulus based on imagination, ie, what image is evoked by the stimulus. With such a system, the final descriptive terminology used would more often than not be expressed in esoteric language, causing confusion and even communication breakdown. The work of Jaubert (1) was the origin of a more standardized descriptive system in the field of aroma description. 

Our immediate and instinctive reaction to an impact or explosion leaves a mental image of utter chaos and destruction. There may be a fascination with the power of such events, but our limited time resolution and limited pressure-sensing abilities cannot provide direct information on the underlying orderly mechanical, physical, and chemical processes. As with other phenomena not subject to direct examination by our human senses, the scientific descriptions of shock and explosion phenomena rest upon a collection of images of the processes which are derived from a range of experiences. The three principal sources of these images in shock science—experiment, theory, and numerical simulation—are indicated in the cartoon of Fig. 3.1.

The reason for the success of this type of data fitting is that for moderately large barriers it becomes unimportant whether escape for the image potential is treated within the framework of the Onsager or the RS model. An indication that the Onsager description is, nevertheless, more appropriate is the intersection of j(/ ) curves for variable temperature at high electric fields. This is a characteristic feature of Onsager processes 24J.

This componnd has hve stereocenters, so it will have many diastereomers (compounds where only some of the wedges have been inverted). There are many, many possible componnds that fit that description, so this compound will have many brothers and sisters. Bnt this compound will only have one twin—only one enantiomer (there is only one mirror image of the componnd above) ...
