-## Ideas

+## Approach
 Since we only serve a static assets and the output is downscale only, I think it's good to pre-process each image to [image integral](https://en.wikipedia.org/wiki/Summed-area_table) first and then save it to another directory (eg. temp).
 
 Later, we can apply Box Filter averaging on the fly to output Stream (HttpResponse).
 
-## Approach
-
-This project is heavily depends on Memory Mapped File to reduce processing overhead and memory pressure to allow HTTP serve more request.
-The MMF is used to store the Image Integral of provided asset.
