一、fMRI的空间分辨率 fMRI的空间分辨率的细粒度在原则上是比较不错的,它取决于BOLD的点分布和信噪比,而这些因素又建立在磁场强度、线圈到组织的距离和脉管系统。空间分辨率的上限大约在400微米左右,其实现条件是强磁场、高分辨率成像或者植入线圈(这个植入就不能在人类大脑上做啦,太恐怖了)。 举个例子来演示一下fMR...
a formal theory of spatial and temporal resolution of observations underlying geographic information. The theory has a dual importance: (i) at the theoretical level, it is to be taken as a small and necessary piece of the science of scale; (ii) at the practical level, the axioms of the t...

locations with fire activity associated with specific meteorological conditions that are not appreciable at the monthly temporal resolution, are probably not well identified. For example, a week of extremely high temperatures could be almost unnoticeable in the monthly mean temperature, but not in fire...
and MODIS data with a general regression neural network, the spatial and temporal resolution was 0.05° and 8 days, respectively. The GLASS LAI values were closer to the mean values of the high-resolution LAI maps, with theR2and RMSE values being 0.81 and 0.78, respectively30. We first ...
Spatial–temporal resolution Radar rainfall X-band radar Urban drainage Hydrodynamic models 1. Introduction The impact of spatial–temporal variability of rainfall on catchment response and the sensitivity of hydrological models to the spatial–temporal resolution of rainfall inputs have been active topics...
9.1.2.4Temporal resolution Temporal resolution is the measure of frequency or repeat cycle where the sensor returns to the same part of Earth’s surface. Here, the characteristics of frequency are obtained by the satellite sensor and their orbit pattern. The frequency of the flyovers by plane or...
The search range. This is the window of pixels in one or more reference frames within which the region of support is compared using the matching criterion, in order to estimate the motion and parameters of the model. The search range will depend on the spatio-temporal resolution of the forma...
