How to compute the receptive field from 3X1 and 1X3?

Answer 3 · 2019-05-09T05:56:59.000Z

That is exactly the same 3x3 convolution. (3x1 conv + 1x3 conv = 3x3 conv)
The reason for doing this is just for the calculation efficiency.
(Very few accuracy dropping with a huge amount of reducing computational complexity)
Reading MobileNet V1 paper will be helpful for you.

I know that. But the receptive field of 1x3 3x1is different with 3x3.------------------ 原始邮件 ------------------ 发件人: "seongkyun"<notifications@github.com> 发送时间: 2019年5月9日(星期四) 中午1:57 收件人: "ruinmessi/RFBNet"<RFBNet@noreply.github.com>; 抄送: "Fanbinqi"<374873360@qq.com>;"Author"<author@noreply.github.com>; 主题: Re: [ruinmessi/RFBNet] receptive field (#105) That is exactly the same 3x3 convolution.
