PSNR:峰值信噪比
“峰值信噪比”(Peak Signal-to-Noise Ratio)在学术论文和电子工程领域中是一个常用的图像与信号质量评价指标,为便于快速书写和引用,通常缩写为PSNR。该术语主要用于衡量经过压缩或处理后的信号与原始信号之间的保真度,数值越高代表失真越小,因此在图像处理、视频编码及通信系统中具有重要应用价值。
Peak Signal-to-Noise Ratio具体释义
Peak Signal-to-Noise Ratio的英文发音
例句
- The experimental results show that the proposed denoising method can achieve high Peak Signal-to-Noise Ratio(PSNR) ( PSNR ).
- 实验表明该方法能取得较高的信噪比,并能保存图像的一些细节信息。
- Experimental results show that the algorithm outperforms the traditional one on both visual quality and Peak Signal-to-Noise Ratio(PSNR) ( PSNR ).
- 实验结果表明,该算法在主观视觉质量和客观峰值信噪比(PSNR)(PSNR)上都优于传统方法。
- The method is tested by the simulated blur image and the captured real blur image, and it is evaluated by the subjective vision and the Peak Signal-to-noise Ratio ( PSNR ).
- 针对模拟和实际采集的降晰图像进行实验,采用主观视觉和峰值信噪比(PSNR)进行评价。
- Experimental results show the correct vectors of camera are reserved while dithers are eliminated, the peak signal-to-noise ratio of smoothed video is higher than that of the original video.
- 实验表明该算法较好地去除了视频序列的高频抖动,同时保留了摄像机的主动运动,稳像后视频序列的峰值信噪比(PSNR)明显提高。
- We also use this method to compress images with program. In the final, we evaluated and analyzed the quality of a series of compressed images with the fuzzy image and PSNR ( Peak Signal-to-Noise Ratio(PSNR) ) measurement.
- 然后用峰值信噪比(PSNR)和本文提出的模糊图像度量分别对一系列压缩后的图像质量进行评价,并且分析了它们的评价结果,最后还进行了对图像添加各种噪声等实验。
