1·Provides better results than Unsharp masking which is built into GIMP.

提供比GIMP内置的锐化掩模更好的效果。

2·I referred some classic algorithms on fingerprint enhancement, such as the fingerprint enhancement by the unsharp masking.

我参考了一些经典的指纹增强算法，如非锐化掩模等。

3·A quadratic unsharp masking (QUM) operator is presented, which extracts edge and detail information from an image with equal weights.

提出了一种二次反锐化掩模算子(QUM)，用于从图像中提取等比重的边缘和细节信息。

4·This method about neural network simulating image unsharp masking process arithmetic can also be used to realize other image process arithmetic.

这种神经网络模拟图像反锐化掩模处理算法的方法也可以用于实现其他图像处理算法。

5·We first employed the unsharp masking to adjust the contrast of angiograms, and then removed the consistent component of low frequency in frequency domain by high-pass filtering.

首先采用反锐化滤波器对血管造影图像进行对比度调整，然后通过频域高通滤波去除背景中的一致性成分。
