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.
