摘要:

A localization algorithm in optical localization nanoscopy plays an important role in obtaining a high-quality image. A universal and objective metric, which is crucial and necessary to evaluate qualities of nanoscopy images and performances of localization algorithms, has not yet been established. The metrics of root mean square error (RMSE or accuracy), precision, recall, and Jaccard index (JAC) are currently used in the literature but in certain conditions fail in distinguishing qualities of different nanoscopy images. In this paper, the root mean square minimum distance (RMSMD) is proposed as a quality metric for localization nanoscopy images. Its properties are analyzed and demonstrated by examples which also show its advantages over RMSE, precision, recall and JAC. As a universal and objective metric, the RMSMD can be broadly applied to applications that need to measure average, local, and mutual fitness of two sets of points.
