Signal noise reduction based on wavelet transform 基于小波变换的信号去噪技术及实现
Sn signal noise 信号噪音比值
Because of increasing dimension of signal / filter , it can suffer stronger signal noise 通过增加信号滤波器的维数,可以容许更强的信道噪声。
In addition , it helps suppress signal noise and assures rich textural detail and natural skin tones 此外, cxprocessiii亦能有效抑制杂讯,保留丰富的质感细节,重现生动自然的肤色。
Raw thermal images acquired by pulsed thermography ( pt ) usually have low signal noise ratio ( snr ) and temperature contrast 摘要脉冲热像检测中直接获取的原始热像往往信噪比较低、对比度较差。
