- 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。 - Experiment results show that in low bit rate environment , the new image compression scheme performs better than jpeg in the aspects of perception and psnr ( peak signal noise ratio )
實驗結果表明該算法在低碼率下，相比jpeg ，獲得了在視覺效果和峰值信噪比方面更好的恢復圖像質量。 - Finally , by using mismatched filter technique , optimized code is studied and searched . this kind of code will be used broadly in the future because it has the property of no sidelobe and low snr ( signal noise ratio ) loss
最后，采用失配濾波器技術，研究并計算機搜索了距離旁瓣為零而信噪比損失很小的優(yōu)化碼，該優(yōu)化碼可有良好的應用前景。 - In order to improve signal noise ratio ( snr ) , wavelet denoising is used , and the radar in - pulse characteristics is extracted by wavelet - ridge , radar emitter signal sorting is realized by neural networks
該方法首先對接收到的雷達信號進行小波去噪，達到提高信噪比的目的，然后利用小波脊線法準確提取其脈內特征參數(shù)，最后基于神經網(wǎng)絡實現(xiàn)信號的分選。 - The maximum likelihood estimator ( mle ) approach is an important one in frequency estimation domain . this approach has the merit such as exhibiting best performance and requiring minimum threshold of signal noise ratio in calculation
最大似然頻率估計法是該領域中的一種重要的研究方法；該方法具有估計結果準確，計算所要求的信噪比門限值低等特點。
