torch是PyTorch的核心库,torch.nn.functional提供了许多神经网络的功能,cv2用于图像处理,numpy是Python数值计算的基础库。 3. 定义计算SSIM的函数 SSIM需要先计算亮度、对比度和结构信息。以下是一个计算SSIM的函数实现: defssim(image1,image2,C1=1e-6,C2=1e-6):"""计算SSIM值"""# 转换为浮点数image1=image...
ssim = util.calculate_ssim(img_Sr, img_Hr,)# print(ssim)sum_ssim += ssim max_ssim =max(max_ssim,ssim) min_ssim =min(min_ssim, ssim)print('Average psnr = ', sum_psnr / numbers)print('min_psnr = ', min_psnr)print('Max_psnr = ', max_psnr)print('Average ssim = ', sum_ss...
