r - R中图像的空间频率滤波(spatial frequency filtering of images in R)

Question

I have been using R for a while, but only for pre-processing and statistical analysis.

(我使用R已有一段时间了，但仅用于预处理和统计分析。)

I would like to do some image processing analysis.

(我想做一些图像处理分析。)

Specifically, I want to filter specific spatial frequencies from an image (eg, 8 cycles per image).

(具体来说，我想从图像中过滤特定的空间频率（例如，每个图像8个周期）。)

Something like the image below.

(如下图所示。)

I know that this can be easily done in matlab, but I was wondering whether this can also be done in R. Anyone with experience?

(我知道这可以在matlab中轻松完成，但是我想知道是否也可以在R中完成。有经验的人吗？)

Thanks a lot!

(非常感谢！)
