JPEG image compression algorithm的意思|示意

Given compression efficiency, we selected JPEG image compression algorithm.

考虑到压缩效率，我们选择了JPEG图像压缩算法。

We test the algorithm performance in the cases of single watermark, double watermarks and multi watermarks when different distortions such as JPEG compression, image resizing and cropping are applied.

该文就单水印，双水印以及多水印情形进行了仿真并进行JPEG压缩、图像缩放、剪切等失真测试。

Experimental results show that the proposed algorithm keeps the quality of the image well and is robust enough to JPEG compression, noise, filtering, image scaling, image enhancement etc.

仿真试验结果表明该水印系统不仅较好地保持了图像的质量，而且对JPEG压缩、噪声污染、滤波、图像剪切等操作都显示了较强的鲁棒性。

The image compression standard in PACS now is the JPEG standard based on the DCT (Discrete Cosine Transform) algorithm, which can only be applied in the limited areas.

目前在PACS系统中较多采用的是JPEG图像压缩标准，该标准采用以离散余弦变换算法为主的区块编码方式，但有一定的局限性。

The experiments show that the blind watermarking algorithm is robust in JPEG image compression, image clipping, image scaling and image filtering, especially in wavelet image compression.

实验结果表明，该算法对JPEG压缩及图像剪裁、缩放、滤波有较好的鲁棒性，特别对于基于小波压缩算法的图像具有很好的鲁棒性。

JPEG has been one of the most popular compression standards of digital image. It is ensured that the watermarking algorithm is very robust against image compression, especially JPEG compression.

这就保证了水印算法对有损压缩具有极好的鲁棒性，特别是JPEG压缩。
