超分辨率（SRCNN）練習

PSNR:

峯值信噪比（PSNR）直接借鑑參考程序會報錯：

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

'Tensor' object has no attribute 'log10'

查閱Keras文檔和TensorFlow文檔後，發現裏面並沒有log10函數，只有log，所以將程序改爲如下即可成功（參考Tensor）：

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

路徑：

在colab中要用到其他文件夾下的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，但今天運行會報錯，修改路徑後又成功運行了。

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

方法一（雙三次採樣）：

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

 輸入和輸出的圖片看起來沒有明顯的差別，暫時不知道原因。

方法二：

該種方法主要區別在於處理數據階段，即在縮小放大時沒有使用兩次雙三次，不同代碼如下：

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