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。
in this paper, the unsharp masking method of image enhancement is discussed.
如何解决这个问题一直是图像增强领域的一个研究热点。
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。
