Using ArcGIS to filter cells where 7 or 8 of neighbors are different

[المشرف العام]

I have land cover data that I would like to clean using some generalization tools. Majority filter does almost exactly what I want, but is missing one key option. Majority filter allows you to change cells where 5 out of 8 of the neighbors are a different class. The problem is that in my data there are many instances when 5 out of 8 is too aggressive. I would like to only target those cells that are surrounded by 7 or 8 different neighbors.

Is there a way to do this in ArcGIS?
