| 摘 要： | 采样数据的增加究竟有多少相应的有效Fisher信息增益,这是测量数据处理、图像数据融合等应用领域中关心的问题.以(共轭)正态分布为基础,利用统计推断理论,导出一定相关性下样本数据的增加与统计信息(Fisher信息)增益之间的关系,并经一维航天测量数据和二维图像超分辨仿真算例验证.

| Abstract: | In the applied fields of data processing and image superresolution, one problem concerned is the measurement of statistical information gain when adding sample points. Based on common normal (conjugated) distribution, this paper investigates the relation between the Fisher information gain and the addition of sampled data that is relevant to previous sample points. And it is validated by simulation of space flight data and image superresolution. |

| Keywords: | fisher information gain sampling rate measurement |
