摘要
借用光学滤波系统理论,对对称图像相减的数学模型进行推广,得出了傅里叶变换实现非对称放置两个图像相减的数学表达式,诠释了其物理意义,规范了其适用范围和使用条件。计算机模拟实验验证了结论的可靠性与可行性。该结论对信息处理、图像识别等具有实用价值。
By generalizing the concept of symmetric image subtraction, build mathematic mold of dissymmetric image subtraction, deduced mathematic expression of image subtraction, elaborated theirs＇ physical meaning, and standardized theirs＇ applicable range and condition. The computer simulation proved the result is reliable and feasible. The result has the practical value in processing information, imaging quality assess etc.
