spatial function
1Spatial ecology — is a specialization of ecology and geography that is concerned with the identification of spatial patterns and their relationships to ecological events. In spatial ecology, ecological events can be explained through the detection of patterns at a …
2Spatial anti-aliasing — In digital signal processing, spatial anti aliasing is the technique of minimizing the distortion artifacts known as aliasing when representing a high resolution image at a lower resolution. Anti aliasing is used in digital photography, computer… …
3function — 1. The special action or physiologic property of an organ or other part of the body. 2. To perform its special work or office, said of an organ or other part of the body. 3. The general properties of any substance, depending on its chemical …
4Spatial query — A spatial query is a special type of database query supported by geodatabases. The queries differ from SQL queries in several important ways. Two of the most important are that they allow for the use of geometry data types such as points, lines… …
5Spatial relation — A spatial relation specifies how some object is located in space in relation to some reference object. Since the reference object is usually much bigger than the object to locate, the latter is often represented by a point. The reference object… …
6Spatial normalization — In neuroimaging, spatial normalization is an image processing step, more specifically an image registration method. Human brains differ in size and shape, and one goal of spatial normalization is to deform human brain scans so one location in one …
7Spatial cutoff frequency — In optics, spatial cutoff frequency is a precise way to quantify the smallest object resolvable by an optical system. Due to diffraction at the image plane, all optical systems act as low pass filters with a finite ability to resolve detail. If… …
8Spatial acceleration — In physics the study of rigid body motion provides for several ways of defining the acceleration state of a rigid body. The classical definition of acceleration entails following a single particle/point along the rigid body and observing its… …
9Wave function — Not to be confused with the related concept of the Wave equation Some trajectories of a harmonic oscillator (a ball attached to a spring) in classical mechanics (A B) and quantum mechanics (C H). In quantum mechanics (C H), the ball has a wave… …
10Optical transfer function — The optical transfer function (OTF) of an imaging system (camera, video system, microscope etc) is the true measure of resolution (image sharpness) that the system is capable of. The common practice of defining resolution in terms of pixel count… …
