超分辨率（SRCNN）练习

PSNR:

峰值信噪比（PSNR）直接借鉴参考程序会报错：

return -10.*numpy.log10(k.mean(k.square(y_pred - y_true)))

'Tensor' object has no attribute 'log10'

查阅Keras文档和TensorFlow文档后，发现里面并没有log10函数，只有log，所以将程序改为如下即可成功（参考Tensor）：

return 10.0*k.log(1.0/(k.mean(k.square(y_pred-y_true))))/k.log(10.0)

路径：

在colab中要用到其他文件夹下的py文件，可以使用：

import sys
sys.path.append("drive/My Drive/GoogleAI/")

之前使用上述方法可行，但今天运行会报错，修改路径后又成功运行了。

import sys
sys.path.append("drive/My Drive/GoogleAI")

方法一（双三次采样）：

import sys
sys.path.append("drive/My Drive/GoogleAI")

输入和输出的图片看起来没有明显的差别，暂时不知道原因。

方法二：

该种方法主要区别在于处理数据阶段，即在缩小放大时没有使用两次双三次，不同代码如下：

lr_img = cv2.resize(cv2.resize(hr_img, (w//3, h//3), interpolation=cv2.INTER_AREA),(w, h), interpolation=cv2.INTER_CUBIC)

predict的scale为2时，这种方法的输入和输出有明显的区别，但是将scale改为3，就没什么明显的区别。这种方法的结果比双三次的要好。
