感谢您的工作,我在训练中遇到一些问题,想向您请教一下
1.请问在选择不同的放大倍数,sig_min/max是否要设置不一样的范围?例如: [0.2,2.0], [0.2,3.0] and[0.2,4.0] for ×2/3/4 SR
2.在训练加 Noise的退化时,--noise需要设置成25还是其他值?
3.Table3中
tab3
对应的模糊核参数(致使其高矮胖瘦,旋转角度),lambda_1,lambda_2,theta,您分别设置的是多少?
在此表示十分感谢!

Hi @Lewis0427, 感谢对我们工作的关注。

  1. 是的,不同放大倍数训练的时候需要设置不同的sig_min/max范围,具体描述在Sec4.1的第一段。
  2. 训练时--noise设置为25就行,random为true的时候会随机生成noise level在[0, 25]范围的高斯噪声(code)。
  3. 请参考这里
