图像的感知质量测量
我目前正在研究图像去噪算法。我需要将我的算法与其他现有算法进行比较,但要做到这一点,我需要一个良好的质量衡量标准。
这种措施的主要目标是接近人类的感知能力。我知道,这几乎是不可能的,但是对于音频信号有很好的感知措施。有没有类似的图像算法?
现在我正在使用简单的测量,例如均方误差(MSE)、信噪比(SNR)等...
供您参考,我目前正在 matlab 中实现此功能
I'm currently working on algorithm for denoising images. I need to compare my algorithm with other, existing algorithms, but to do so I need a good quality measure.
The main goal for such measure is to be close to human perception skills. I know, that it is almost impossible, but there are good perceptual measures for audio signals. Are there any similar algorithms for images?
Right now I'm using simple measures, such as mean squared error (MSE), signal to noise ratio (SNR) etc...
And for your information, I'm currently implementing this in matlab

您检查过 SSIM (http://en.wikipedia.org/wiki/Structural_similarity) ?以下页面 (http://www.ece.uwaterloo.ca/~z70wang /research/ssim/)为您提供了一个真实的示例,说明 SSIM 与 MSE 相比如何工作。
