By using F-P(Filter-Pipeline) model

this paper proposed a way to stitch multi-projector displays in real-time video processing The model takes multithreading technology which can process several frames at the same time It ensures that the video can be played fluently with a high quality effects With this model

the system can be easily constructed based on the common PCs and benefits us with reduced cost Furthermore

the system constructed with F-P model can adapt to a new environment with the extensibility to add or change the filters in the model Here

this paper also gives two examples in designing “geometrical transform filter” and “edge smoothing filter” and approved to be well done in real-time video processing
