Furthermore, we extend the use of DCT, and give a new algorithm on imagepartition and singular points location.
另外，基于DCT变换提出了新的指纹图像分割算法和奇异点定位算法。

In the process of the real-time imagepartition, using the eigenfunction to realize the partition of image coordinate set is very convenient and easy.
在实时图像分割的过程中，利用特征函数实现图像坐标集合划分简便快捷。

Experimental results shows that obtaining threshold by imagepartition and restricting the range of the modulus can accomplish better edge detect results.
