测试以下图像信息 1。结构内容（SC） 2。均方误差（MSE） 3。峰值信噪比（PSNR值） 4。归一化互相关（NCC） 5。平均差（AD） 6。最大的差异（MD） 7。归一化绝对误差（NAE）(Image/Picture Quality Measures In this application, different image quality measures are calculated for a distorted image with reference to an original image. To test the application, a set of 20 distorted images is included in this package. The list of Image Quality measures implemented in this package include, 1. Structural Content (SC) 2. Mean Square Error (MSE) 3. Peak Signal to Noise Ratio (PSNR in dB) 4. Normalized Cross-Correlation (NCC) 5. Average Difference (AD) 6. Maximum Difference (MD) 7. Normalized Absolute Error (NAE) Refer Reference.png for the mathematical expressions implemented in this package. Original images are kept in the folder OriginalImages . Distorted images are kept in the folder DistortedImages .)
