Rotoscopy

The rotoscopy is in the beginning a technique of animation creates by Dave and max Fleischer in the neighborhoods of 1914, consisting in transforming a scene filmed into a cartoon. It makes it possible to obtain more fluid animations with made natural. This process was in particular used in the cartoon of the Seigneur of the Rings .

The traditional rotoscopes used a table of transparent projection, on which each image of film appeared. The draftsman could then follow contours of the really filmed forms and redraw them on a suitable copy.

Nowadays, with the use of the graphic computer tools, the term rotoscopy means the final improvement or manual cutting, image by image, of a digitized film, in order to remove certain elements of them or to add others of them, in particular of decoration.

For example, for a historical film, a plan will be turned with dressed up actors, in a natural landscape. One will wish to remove anachronistic elements appearing at a place, or frankly to change a whole background for esthetic reasons. Using suitable software (but it is about a manual work) of the computer graphics experts will come to modify initial film by preserving only what the realizer wishes. One will be able to then incorporate other elements in it (natural or generated by computer).
