Moire Patterns is an alternating and repeating blurred and clear areas of subject matter with uniform thin stripes or small polka dots, as seen on the screen. This occurs because the stripes or dots on the subject are spaced slightly differently from the scan lines or pixels on the screen and some of these features line up with the scan lines or pixels while others don't.

scanned images from printed material like magazines has a v.special problem.you will discover little dots in ur scanned images frm printed material.the interference is called moire pattern.in a scanned image moire patterns are caused by interfernce between two stes of fine patterns grid.

A moiré pattern is an interference pattern created, for example, when two grids are overlaid at an angle, or when they have slightly different mesh sizes.
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. This cause of moiré is a special case of aliasing, due to undersampling a fine regular pattern.
The drawing on the right shows a moiré pattern. The lines could represent fibers in moiré silk, or lines drawn on paper or on a computer screen.

well kajol, Moiré patterns often occur when scanning newspaper or magazine pictures. These patterns will appear as wavy or rippled lines across the finished ,(Pronounced "mo-ray") irregular plaid-like patterns that occur when a bit-mapped image is reduced, enlarged, displayed, or printed at a resolution different from the resolution of the original.

Moiré patterns often occur when scanning newspaper or magazine pictures. These patterns will appear as wavy or rippled lines across the finished scanned image. This is due to the type of paper and ink used on these originals. Pictures with small checkered patterns, or even tweed jacket types of design may also produce these moiré patterns. See “Reduce Moiré Patterns”.

When you overlap materials with repetitive lines, you create moire patterns.When you look through one chain-link fence at another, you sometimes see a pattern of light and dark lines that shifts as you move. This pattern, called a moire pattern, appears when two repetitive patterns overlap. Moire patterns are created whenever one semitransparent object with a repetitive pattern is placed over another. A slight motion of one of the objects creates large-scale changes in the moire pattern.

hi kajol:-
A moiré pattern (pronounced /mwɑːˈreɪ/ or /ˈmɔəreɪ/ in English; [mwaʁe] in French) is an interference pattern created, for example, when two grids are overlaid at an angle, or when they have slightly different mesh sizes.

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. This cause of moiré is a special case of aliasing, due to undersampling a fine regular pattern.

The nonlinear interaction of the optical patterns of lines creates a real and visible pattern of roughly horizontal dark and light bands, the moiré pattern, superimposed on the lines.[1] More complex line moiré patterns are created if the lines are curved or not exactly parallel. 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. One of the most important properties of shape moiré is its ability to magnify tiny shapes along either one or both axes, that is, stretching. A common 2D example of moiré magnification occurs when viewing a chain-link fence through a second chain-link fence of identical design. The fine structure of the design is visible even at great distances.

Morie Pattern is an interference pattern created, for example, when two grids are overlaid at an angle, or when they have slightly different mesh sizes.

In computer graphics, a visible distortion. It results from a variety of conditions; for example, when scanning halftones at a resolution not consistent with the eventual printed resolution or when superimposing curved patterns on one another. Internal monitor misalignment can also be a cause. The term comes from the French "moirer" (to water) and is used to express a rippled, water-like look, which is often a desired artistic effect.
