用光学方法实现么正变换及一般线性变换(Ⅳ)——图形识别及投影算子

本文指出,图形识别实质上是图形空间中的表象变换(坐标系变换)。由于表象变换是通过么正变换实现的,用光学方法进行图形识别是比较合适的。本文着重讨论了如何只根据所需识别的标准图形组,构造光学系统,即用光学方法直接实现投影变换的方法。并进一步发展了文献3]中的优化方法。 关键词：

UNITARY TRANSFORMATION AND GENERAL LINEAR TRANSFORMATION BY THE OPTICAL METHOD (Ⅳ)——THE PATTERN RECOGNITION AND PROJECTION OPERATOR

In this article, it has been pointed out that the pattern recognition is the representation transformation in pattern space. As it is well known, in Hilbert space, the representation transformation is realized by the unitary operator, so it is more suitable to use the optical method for pattern recognition. Further more, we have discussed the method with which one can construct the optical system only from the characteristic patterns, In reality, this problem is to realize the projector by optical method. We also have advanced the optimization method in 3].
