Pixel Normalization tensorflow impliment

您好,最近尝试用tf复现您的工作,尝试通过method: tf.keras.GroupNormalization() 实现。有以下两个疑问

  1. 对于[B, H, W, C ]形状的输入, pxiel norm 计算了多少次均值和方差呢, B x H x W次还是 H x W 次? 结合您的paper和code,我觉得是前者,也就是不同照片同一位置的像素分别计算了不同的均值和方差。 请问是这样吗?

  2. tf官方API没看懂axis参数指定多个dim到底是啥意思 -> API文档地址,试了下面两种都不对 :( ,有空的话帮看下吧

    • tf.keras.GroupNormalization(groups=d_model, axis=-1, epsilon=1e-8,) # 默认输入 x [B , H , W , C]
    • tf.keras.GroupNormalization(groups=B * H * W, axis= (0,1,2), epsilon=1e-8,) # 默认输入 x [B , H , W , C]

谢谢 !

Multi-Adds

您好,您的Multi-Adds是怎么计算出来的呢?我使用torchstat计算出来的结果和论文上的不一样

速度还是有点慢

虽然参数量少,但推理速度还是太慢了,转成tensorrt后在同样的机器上,360p的输入只有50多fps,vapsr-s版本也只有80多fps,RFDN的速度可以达到130fps左右

Parameters of the model,

Hello author, I like your work very much, but now I have a problem. I used the profile to calculate the Parameters of the model, but in the case of X4, the calculated value is 440K. Is my calculation method wrong? Please advise, thank you
