Mouse teeth or herringbone pattern is the term for a distortion arising from deinterlacing video. They occur when two frames combined for deinterlacing are noticeably different. Similar distortions may also be referred to as tearing or line crawling.
This distortion is most noticeable when there is horizontal movement between the two frames, as the lines in the newer frame will be shifted in the direction of motion from the older frame. When the frames are combined a jagged edge (mouse teeth) will be formed.
Famous quotes containing the words mouse and/or teeth:
“It is as when a migrating army of mice girdles a forest of pines. The chopper fells trees from the same motive that the mouse gnaws them,—to get his living. You tell me that he has a more interesting family than the mouse. That is as it happens.”
—Henry David Thoreau (1817–1862)
“No spoon has yet destroyed a mouth, but the knife of war cuts portions that are hard to swallow. Perhaps the big mouths of the privileged are able to cope with them, but they dull the teeth of the little people and ruin their stomachs.”
—Franz Grillparzer (1791–1872)
