高频

In the first frame, ROI of high-frequency subbands was detected by morphological Harr wavelet lifting and connectivity analysis.

在第一帧内，利用形态Harr小波提升和连通性分析检测出高频子带中的感兴趣区域。

This thesis proposes a lossless digital watermarking algorithm based on Harr wavelet transform, which can recover the original image without any distortion from the marked image after the watermark has been extracted.

提出了基于Harr小波的彩色图像可逆水印算法，采取闭环控制自适应地修改其高频子带系数以嵌入水印。

Objective: To sum up the discourses concerning acupuncture prescriptions for disorders of blood (epistaxis, hematochezia, hematuria, hematemesis) in the medical literature from ancient to modern.

目的：归纳古今医学文献中有关血证(鼻衄、便血、尿血、吐血)针灸处方的相关论述，统计诸血证处方中不同穴位出现的频次，总结出各血证的高频次主治穴位。

Tesla's wireless and communications system did not use Hertzian waves to broadcast but rather used the EARTH as a carrier for the electromagnetic and high frequency waves.

特斯拉的无线通信系统和没有使用赫兹波广播，而是使用了地球承运人的电磁和高频波。

Then we can determine three reconstructed parameters in terms of average period. The results of EEG analysis show: The largest Lyapunov exponent of EEG data which corresponds to the hippocamp area is bigger than others.

这些预处理包括：利用FFT滤掉EEG数据的高频和低频部分，用关联维来代替EEG数据的原始拓扑维，最后根据平均周期来确定三个重构参数。

Based on the study of the traditional homomorphic algorithm,the most effective high-pass filter in frequency domain is adopted.

因此在研究传统同态滤波算法，选取性能最佳的频域滤波器对图像进行处理的基础上，引入了空域3×3中值滤波，用像素点3×3邻域内9个像素点的中值来代替该点的像素值，旨在对前者无法去除的高频突变云区进行处理。

Objective To explore the value of high frequency ultrasound in congenital hypertrophic pyloric stenosis.

目的 探讨高频超声在先天性肥厚性幽门狭窄中的应用价值。

Methods:We ablated the ventricular tachycardia of 12 patients with normal hearts by the catheter, using pace mapping and activation sequence mapping. The former original target was the site where the pacing QRS was entirely consistent with IVT(Idiopathetic Ventricular Tachycardia) attack. And the latter original target was the site of in advance of earliest high frequency and low amplitude local potential on surface electrocardiogram QRS≥20ms, using activation sequence mapping. Results: Among 12 patients, the IVT originated from right ventricle in 2 patients, from left ventricle in 10 patients.

对12例正常心脏室速进行导管消融，采用起搏标测与激动顺序标测，前者以起搏时与室速QRS波型形态完全相同，后者以激动顺序标测法定位，以记录心动过速时较体表心电图QRS提前≥20ms的最早高频低振幅局部电位处为消融靶点，结果：12例患者室速起源部位分别为：右心室2例，左心室10例，疗效100%。
