| 摘 要： | 不等精度的观测数据可能对图象产生较大的干扰，等概率归一法是建立在概率统计理论基础上的，适合于对任何服从正态分布的随机变量做归一化处理。归一化以了从同一正态分布，可以减少或消除不等精度的干扰，突出图象中的有用信息。

| Abstract: | The data observed with unequal precision may significantly interfere with images. A new method to eliminate the image interference is the equiprobability normalization method which is based on the theory of probability statistics and can be employed to normalize the random variables defying normal distribution. The normalized data will exhibit the same normal distribution, reduce or eliminate the interference of unequal precision, and highlight the useful information in images. |
