接下来,我们可以定义一个计算PSNR的类,代码如下: importcv2importnumpyasnpclassPSNRCalculator:def__init__(self,original_image_path:str,compressed_image_path:str):self.original_image=cv2.imread(original_image_path)self.compressed_image=cv2.imread(compressed_image_path)defcalculate_mse(self):ifself.origi...
print(f"PSNR值:{psnr_value:.2f}dB")# 输出 PSNR 值,保留两位小数 1. 类图 在这个程序中,我们创建了两个主要的类:ImageProcessor用于处理图像,PSNRCalculator用于计算 MSE 和 PSNR。下面是类图的表示: ImageProcessor+read_image(path: str) : ndarrayPSNRCalculator+calculate_mse(original: ndarray, reconstruct...

上述代码首先通过ImageIO类读取原始图像和待比较图像,然后使用calculateMeanSquareError方法计算均方误差,最后通过calculatePSNR方法计算PSNR值,并输出结果。 序列图 下面是计算PSNR的示例代码的序列图: FileBufferedImageImageIOPSNRCalculatorUserFileBufferedImageImageIOPSNRCalculatorUser执行计算PSNR...
