The alias effect is a phenomenon that occurs when digital cameras fail to accurately reproduce detailed patterns. This often results in unusual visual artifacts in photos or videos. For instance, when photographing narrow striped or patterned clothing, new wavy or swirly patterns may appear in the ...
(,ΔCC)VREF2∆CCVREF2 indicates the unwanted jump in the residue transfer curve. This vertical shift introduces missing codes in the overall ADC output and results in substantial harmonic distortion at the output. The effect of the gain error on the residue characteristic obtains the gain ...
A digital relay and concomitant method comprising employing an analog-to-digital converter, and via control logic providing oversampled output of the converter to determine likely digital values corresponding to the output, and wherein the control logic substantially eliminates aliasing resulting from wave...
"Aliasing" refers to the fact that many points (which would differ in the real image) are mapped or "aliased" to the same pixel (with a single value) in the digital representation. This article is provided by FOLDOC - Free Online Dictionary of Computing (foldoc.org) ...
In general, moire effects appear simply because the image is discretized into square pixels. As such, they are inherent to digital images. The effect can be reduced through the usage of different anti-aliasing filters, but is not completely avoidable. ...
In this paper we present a method to design beamformers that overcome the effect of spatial aliasing by suppressing the undesired side-lobes through signal processing without physically modifying the configuration of the array. This is achieved by modeling the expected aliasing pattern in a maximum-...

This has the effect of anti-aliasing the silhouette of the object. Other aspects will become apparent from the following detailed description when taken in conjunction with the drawings, in which: BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram representing a computer system into...
A need has therefore arisen for a method and apparatus that is capable of detecting aliasing frequency components, determine their effect to the signal within the frequency band of interest, and eliminate the aliasing frequency components. SUMMARY OF THE INVENTION ...
The term “depth window” may be used to refer to the depth that can be detected without encountering the aliasing effect. For example, the depth window could be 2.5 meters for a given camera. One de-aliasing technique is to modulate the light at several different frequencies. For each ...
