frequency-domain filtering

基本解釋

Then the system model of the traditional time-domain LMS and frequency-domain block LMS adaptive filtering algorithm was built.
然后對(duì)時(shí)域傳統(tǒng)LMS自適應(yīng)濾波算法和頻域塊LMS自適應(yīng)濾波算法進(jìn)行系統(tǒng)建模；
Secondly a block-based frequency-domain LMS adaptive filtering algorithm was introduced and analyzed based on the traditional time-domain algorithm.
其次在時(shí)域傳統(tǒng)算法的基礎(chǔ)上引出一種基于頻域的塊LMS自適應(yīng)濾波算法，并完成其性能分析；
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.
首先采用反銳化濾波器對(duì)血管造影圖像進(jìn)行對(duì)比度調(diào)整，然后通過(guò)頻域高通濾波去除背景中的一致性成分。
