5: Subsampled image showing a Moiré pattern

Moiré is where an interference pattern is produced by fine scene detail beating with the line ( or even pixel ) structure of the device used to analyse or display the scene.

Moiré patterns are often an undesired artifact of images produced by various digital imaging and computer graphics techniques, for example when scanning a halftone picture or ray tracing a checkered plane ( the latter being a special case of aliasing, due to undersampling a fine regular pattern ).

Moiré patterns are commonly seen on television screens directly when a person is wearing a shirt or jacket of a particular weave or pattern, such as a houndstooth jacket, due to sampling problems in the television camera.

As the person moves about, the Moiré pattern is quite noticeable.

Spatial aliasing in the form of a Moiré pattern.

An example of spatial aliasing is the Moiré pattern one can observe in a poorly pixelized image of a brick wall.

The blur makes the image less sharp, but prevents the formation of Moiré pattern aliasing artifacts.

* Moiré pattern, a form of spatial interference that generates new frequencies.

The pattern seen on screen can at times be similar to a Moiré pattern.

Moiré patterns revealing complex shapes, or sequences of symbols embedded in one of the layers ( in form of periodically repeated compressed shapes ) are created with shape moiré, otherwise called band moiré patterns.

A color-blind person who approaches Tipperary Hill, not knowing about the different color pattern at that particular traffic light, could cause a severe accident by seeing the light at the bottom and assuming it is green when it in fact is red, or vice versa.

Starting at the bottom and ( in the Galician fingering pattern ) progressively opening holes creates the diatonic scale.

The miniature H. papilio ( which is a true species, i. e., not a cultivar or hybrid but the actual plant that grows in the wild ) has a unique color and pattern with broad rose-burgundy center stripes and striations of pale green on the upper petals and narrow stripes on the bottom three.

Early automatic transmissions, including GM's Hydra-Matic, Packard's Ultramatic, and Borg Warner's automatic used by a number of independent manufacturers ( Rambler, Studebaker ) used a pattern of " P N D L R " which put Reverse at the bottom of the quadrant, next to Low.

The bottom section of the test pattern contains a square of saturated ( 100 % intensity ) white and a rectangle of saturated ( 7. 5 % intensity ) black, for use in setting the luminance range.

Also in the bottom section are two sections that contain-Inphase and + Quadrature signals ( see YIQ ), centered on black level and having the same gain as the color burst signal ; these show up on the pattern as a square of very dark blue, and a square of very dark purple.

Starting at the bottom and ( in the Galician fingering pattern ) progressively opening holes creates the diatonic scale.

In some instances lines are written horizontally so as to match the text to divinatory cracks, or columns of text rotate 90 degrees in mid stream, but these are exceptions to the normal pattern of writing, and inscriptions were never read bottom to top.
