k_list设置问题 #22
Comments
感谢关注!简单来说2D频域的绝对值为[0, 1/2] * \pi,此处的2,则是将频域划分为[0, 1/2 * 1/2], [1/2 * 1/2, 1/2],4则是[0, 1/2 * 1/4], [1/2 * 1/4, 1/2],以此类推,论文中4个频道则设[2, 4, 8]即可。 |
好的,感谢作者的耐心解答!!请问您可以再解释一下您提到的mask吗,既然是我们人为设置划分了四段,mask是如何根据预设的频率段来筛选呢?主要是筛选这四段中,每一段的低频信息吗?还有selection map这里和mask有关系吗?感觉不是很清晰这一块,期待您的回复!!! |
Mask只用来分频,选择是通过conv+sigmoid的输出来对每个位置和每个频段做选择 |

尊敬的作者,请问k_list是在空间域的尺度设置吗?k_list您在源代码中设置为2,即对应的freq为2还是1/2呢?含义是否是把输入频率划分为高频(1/2,1)低频(0,1/2),那么论文中的四个频率通道是如何设置呢?感谢感谢,期待您的回复!!!
