The nearest border pixels are conceptually extended as far as necessary to provide values for the convolution. Corner pixels are extended in 90° wedges. Other edge pixels are extended in lines. Wrap The image is conceptually wrapped (or tiled) and values are taken from the opposite edge or corner. Mirror The image is conceptually mirrored at ...
As an example of screen direction in use, if an actor is shown in one shot walking from screen left to screen right and then is shown in the next shot to be moving in the opposite direction (screen right to screen left), the audience will assume that the actor has changed direction and is walking back to where he started (in the absence of ...
