This increased roughness in the enhanced image data serves to increase confidence of the classification analysis for detecting low-frequency halftone screens, so that such low-frequency halftone areas are not misclassified as contone or high-frequency halftone areas....
6.2.2.3 Low-frequency band The LF band range is between 0.04 and 0.15 Hz representing a rhythmic periodicity of 07–25 s, also referred to as the mid-frequency band reflects the baroreceptor activities of heart during rest and helps in maintaining the blood pressure to normal (McCraty and Sh...
Full size image We first restored high-frequency and high-resolution signals from LPF input signals of the MEA1 using the SwinIR and Spk-Recon with different downsampling factors. As shown in the representative raw traces of a single electrode in Fig.3b, both ML models successfully reconstructed...
目的 探讨采用低频振荡振幅(ALFF)法分析伴消极完美主义首发抑郁症患者特征性脑功能改变,并研究其与临床症状的相关性。方法 纳入2020-2022年招募的44例首发抑郁症患者,男11例,女33例,年龄24.64±5.31岁,根据中文Frost多维度完美主义量表(CFMPS)中消极完美主义总分将
High Frequency Restoration Module 论文没有舍弃掉高频的细节信息,为了更细粒度的提升,使用水平方向和竖直方向上的信息补充对角线上的信息; 创新点具体是怎么做的 利用离散小波变换降低数据规模 离散小波变换 对于低光图像 Ilow∈RH×W×3 ,使用Haar小波做离散小波变换2D-DWT,将图像转换为四种不同的频域中,分别是全...

Low-frequency noise may cause changes in cognitive function. However, there is no established consensus on the effect of low-frequency noise on cognitive function. Therefore, this systematic review and meta-analysis aimed to explore the relationship betw
