7. Conclusion

Augmented imagery adds virtual content to existing real video content. This chapter has described basic techniques for augmenting video content and three major example applications. Rapidly advancing processor capabilities are now allowing limited augmentation of content in streams sourced by video database systems. These augmentations could add or change advertisements in order to generate revenue, or they could allow content to be repurposed by changing the locale or background in the sequence. Virtual set technologies allow content to be created with no background at all, leaving the background settings choice as a run-time decision. Augmented imagery merges AR technologies, computer graphics and tracking/identification into systems useful in a wide variety of settings.
