问题描述

朋友，我正在该项目中的一个项目上工作，我想压缩图像，以便创建两个绿色子图像，一个蓝色子图像和一个红色子图像.现在我要使用一个绿色子图像对其进行编码，然后对其进行解码，然后对其进行估计，那么刺激任何人都可以帮助我的解码图像是什么意思.

推荐答案

在图像压缩的情况下，术语估计"最有可能是指估计由压缩/解压缩过程引入的错误.

图像重建质量的一种相当常见的度量是峰值信噪比"或(PSNR).

维基百科给出了合理的解释: http://en.wikipedia.org/wiki/Peak_signal-to-noise_ratio [^ ]

如果您需要比Wikipedia描述更多的帮助，请尝试使用Google搜索"PSNR"或"PSNR估计"

In the context of image compression, the term "estimate" most likely refers to estimating the error introduced by the compression/decompression process.

A fairly common measure of image reconstruction quality is "Peak Signal to Noise Ratio" or (PSNR).

Wikipedia gives a reasonable explanation: http://en.wikipedia.org/wiki/Peak_signal-to-noise_ratio[^]

If you need more help than the Wikipedia description, try Googling "PSNR" or "PSNR estimation"
