Chapter 6. Video Filtering
The performance of single-frame (image) de-noising and restoration methods may be improved by multi-frame filtering, whereas video-format conversion and super-resolution reconstruction are inherently multi-frame filtering problems.
This chapter extends the image-filtering methods covered in Chapter 3 by introducing new methods that are specific to video, including multiple-picture (field or frame) filtering methods. Multi-frame filters can be classified as linear spatio-temporal filters, motion-adaptive filters, and motion-compensated filters. The theory of linear spatio-temporal filtering is provided in Section 6.1. Temporal frequency content of a video is dependent on the spatial-frequency content of a key frame and ...
