分析和研究了一种特殊的形态运算--空间变化开运算的统计行为。空间不变形态运算和空间变化形态运算的主要区别在于，空间不变运算中每个位置对应的结构元素是相同的，而空间变化运算中每个位置对应的结构元素可能是不同的。将一种原本用于分析空间不变开口的常规统计分析方法推广到空间不变开口的分析中。对于有噪声的阶跃边缘的滤波，得到了一些比较分析的结果，结果表明，利用空间变化的开口可以提高边缘保持能力。
The statistical behavior of a special type of morphological operation, the space-varying opening, is analyzed and investigated. The major distinction between the space-invariant morphological operation and the space-varying one is that the structuring element corresponding to each position in the space-invariant operation is the same, but the structuring element corresponding to each position in the space-varying operation may be different. A regular statistical analysis method, which was originally designed for the analysis of the space-invariant opening, is applied and generalized to the analysis of the space-varying one. For the filtering of a noisy step edge, some comparative analytic results are obtained revealing that edge-preserving ability can be improved by the use of the space-varying opening.
