摘要

本文提出了一种具有全局误差控制的目标检测方法。该方法的新颖之处在于既考虑了目标的空间结构,又保证了对像素误差的适当控制。讨论了一个通用框架,并在此基础上实现了一种方法。模拟数据的结果表明,在标称控制水平下,检测功率得到了决定性的增益。该方法还应用于缪斯天文仪器的实测数据。

Global error control procedure for spatially structured targets
In this paper, a target detection procedure with global error control is proposed. The novelty of this approach consists in taking into account spatial structures of the target while ensuring proper error control over pixelwise errors. A generic framework is discussed and a method based on this framework is implemented. Results on simulated data show conclusive gains in detection power for a nominal control level. The method is also applied on real data produced by the astronomical instrument MUSE.
