Hi Marko

Apologies for the late reply. I have been attedning GUADEC, and then 
travelling afterwards, so have only had sporadic access to email.

The effects which are used by Cheese are supplied by 
gnome-video-effects:

https://git.gnome.org/browse/gnome-video-effects/tree/effects

Each effect description includes a GStreamer pipeline, which is what 
transforms the video.

To create your own effect, you need to supply a GStreamer pipeline 
(possible creating a new element if you want something that is not 
available with the current elements), create a new .effect file 
(probably by copying an existing effect) and to place the effect either 
in the system location (/usr/share/gnome-video-effects) or the user 
location (generally ~/.local/share/gnome-video-effects).
