Is it possible to get a conceptual explanation of how the scanning window filter work using the HDL pixel stream interface

I've been going through the generated HDL files and can not pin down how it works exactly, I'd appreciate at least a run down of what every component does, even if just a shallow one so I know where to start digging.

There is is a Line Buffer top module that uses a data memory module, vertical and horizontal padding components in addition to a number of push and pop counters.

The Line Buffer block help page has a brief description of its algorithm. The page also also has an example on how to construct a filter using the line buffer, which is similar to what the Image Filter block does.
