可惜的是Tensorflow没有内置SSIM作为LOSS,因此需要自己动手丰衣足食,动手写一个以SSIM为基准的损失函数,文件名叫tf_ssim_loss.py: def my_ssim_loss(y_true, y_pred): import tensorflow as tf total_loss = 1 - tf.image.ssim(tf.cast(y_true, tf.float64), tf.cast(y_pred, tf.float64), max_v...

For ssim, it is recommended to setnonnegative_ssim=Trueto avoid negative results. However, this option is set toFalseby default to keep it consistent with tensorflow and skimage. For ms-ssim, there is no nonnegative_ssim option and the ssim reponses is forced to be non-negative to avoid ...
