摘要

我们提出并评估了一种使用分段线性逼近生成多维惯性传感器信号压缩表示的方法。该表示可以在小型传感器节点上计算,从而允许减少需要传输到主处理节点的数据量。在现有的手势数据库上,我们给出了达到的压缩率,并根据手势分类所达到的精度来评估表示的质量。我们使用一种更简单的数据缩减方法将结果与基线系统进行比较。

Compressed signal representation for inertial sensor signals
We present and evaluate a method to generate a compressed representation of multi-dimensional inertial sensor signals using a piecewise linear approximation. The representation can be computed on small sensor nodes and thus allows for a reduction of the amount of data that needs to be transmitted to the main processing node. On an existing gesture database, we present the compression rate that is reached and evaluate the quality of the representation in terms of the accuracy reached for gesture classification. We compare the results to our baseline system using a simpler approach for data reduction.
