Morphing slow-motion effects & optical flow technology

Morphing is a special effect in motion pictures and animations that changes (or morphs) one image into another through a seamless transition. In the early 1990s computer techniques that often produced more convincing results began to be widely used. These involved distorting one image at the same time that it faded into another through marking corresponding points and vectors on the "before" and "after" images used in the morph.

















Morphing softwares continue to advance today and many programs can automatically morph images that correspond closely enough with relatively little instruction from the user. This has led to the use of morphing techniques to create convincing slow-motion effects where none existed in the original film or video footage by morphing between each individual frame using optical flow technology.
