采用独特的光源系统，保证图象清晰度，荧光灯管使用寿命长、维护简单方便。 - Two spatially registered images with different focuses are decomposed into several blocks . then , three features reflecting the clear level of every block , i . e . , spatial frequency , visibility , and edge , are calculated . finally , artificial neural networks , i . e . , multilayer - perceptron , radial - basis function , probabilistic neural network , are used to recognize the clear level of the corresponding blocks to decide which blocks should be used to construct the fusion result
具体实现过程概述如下：首先将两幅（或多幅）配准图象进行分块处理，提取两幅图象中对应块的能反映图象清晰度的三种特征，即空间频率、可见度和边缘，将特征归一化后送入训练好的神经网络进行识别，根据得到的结果依据“谁清晰谁保留”的原则构成融合的图象。
