ABSTRACT
Complex heterogeneous sensor networks that include both
traditional scalar and richer video data are becoming possible.
With such technologies comes the task of making them useful to
the applications that rely on them. Unfortunately, such applications
are extremely diverse in the interaction requirements of the
system components. This paper argues that the system software
for such sensor systems needs to balance optimization for performance
and providing a flexible interface that can be tailored
to the requirements of the user application. We propose Cascades,
a cascading filter mechanism that can allow users to
quickly compose and re-task diverse sensor systems (which
include both scalar and video-based sensors) with highly optimized
application-specific algorithms.

摘要
包含傳統(tǒng)標(biāo)量和更豐富的視頻數(shù)據(jù)的復(fù)雜的異構(gòu)傳感器網(wǎng)絡(luò)成為了可能。實(shí)現(xiàn)該技術(shù)隨之而來的任務(wù)，是使它們成為有用的應(yīng)用程序從而依賴它們。不幸的是，這種應(yīng)用需要該系統(tǒng)的組成部分有極其多樣的互動(dòng)要求。本文認(rèn)為，該傳感器系統(tǒng)的系統(tǒng)軟件需要平衡優(yōu)化性能并提供一個(gè)靈活的接口，可以進(jìn)行調(diào)整，以適應(yīng)用戶的要求申請(qǐng)。我們建議級(jí)聯(lián)，級(jí)聯(lián)過濾機(jī)制可以讓用戶使用高度優(yōu)化的特定應(yīng)用的算法快速編寫及轉(zhuǎn)口任務(wù)多樣的傳感器系統(tǒng)（其中包括基于視頻傳感器的兩個(gè)標(biāo)量）。
