Some questions about feature map size matching.

[xiaoxiaoze]

Hello, I want to ask you some questions about the matching of feature map size.
For example:
Input an 256X256 size image
First Conv2D output 16X128X128 size feature map
Second Conv2D output 32X64X64 size feature map
Then we want use the Res_block(short_cut) to match the channel and feature map size.
can we use 3X3 kernel, 32 channel, strides=2, Conv2D, to match the feature map size?
I am not sure about it.
