What are the two types of imagery discussed in class?

• A. Infrared and visible imagery
• B. FMV and Still imagery
• C. Still images and video frames
• D. FMV and infrared imagery

Answer: (B)

The concept being tested is the distinction between moving imagery and static imagery. Full Motion Video is a sequence of frames that shows motion over time, capturing how things change and move, which is essential for analyzing events, behavior, or dynamics. Still imagery, on the other hand, is a single frame captured at one moment, providing detailed spatial information but no motion information. Knowing when to use FMV versus a still image helps you choose the right data for either tracking and motion analysis or detailed examination of a single moment. The other options mix different modalities (like spectra) or treat individual video frames as a separate category, which doesn’t reflect the moving-vs-static distinction the question is about.
