Signal noise reduction based on wavelet transform 基于小波變換的信號去噪技術(shù)及實現(xiàn)
Sn signal noise 信號噪音比值
Because of increasing dimension of signal / filter , it can suffer stronger signal noise 通過增加信號濾波器的維數(shù),可以容許更強的信道噪聲。
In addition , it helps suppress signal noise and assures rich textural detail and natural skin tones 此外, cxprocessiii亦能有效抑制雜訊,保留豐富的質(zhì)感細(xì)節(jié),重現(xiàn)生動自然的膚色。
Raw thermal images acquired by pulsed thermography ( pt ) usually have low signal noise ratio ( snr ) and temperature contrast 摘要脈沖熱像檢測中直接獲取的原始熱像往往信噪比較低、對比度較差。
