- 数字图像放大缩小及旋转计算组间方差和组内方差的时候调用了一个函数专门求阈值,可能这里的计算还是有一点问题。而且在我的函数里,要256次调用这个函数,又因为计算机是按字节处理数据的,因此写图像数据的时候要用每8个写到一个数组中,然后通过计算得到字节类型的值,这些都使得我的算法效率比较低,最后一个问题,我觉得如果使用位运算会快一些,但是前面的问题还没有想到比较好的解决方法。-Digital Image zoom and rotation calculation of variances and gr

- 由于光线分布不均匀或斑块噪音干扰等原因,往往使所要处理的指纹的灰 度值分布缺乏均匀性。在指纹特征自动识别提取过程中,造成许多传统的算法在局部出 现很大的误差。利用方差和均值特征的自动提取方法,首次对不均匀灰度图像进行自适 应分割。然后通过对图像分区域进行不同程度的自适应调整,使具有相同属性的像素单 元具有近似的灰度值分布。调整结果的灰度均匀水平与预先指定的调整精度成正比。这 种调整不仅提高了图像分割的自适应性,而且进一步扩大了一般阈值算法的应用领域。-Gray value d
