WebSep 12, 2011 · The visual errors and artifacts created are what we call “aliasing.”. The second and third images above use different forms of “anti-aliasing” to better approximate how human eyes (and cameras) perceive light. Those images, however, were a translation of absolute mathematical images into pixel based images. How does anti-aliasing apply ... WebJun 19, 2012 · The kind of aliasing you deal with in digital photography happens when detail in the image, when projected onto the sensor is roughly the same size or smaller than a single pixel in the sensor. This can lead to Moire patterns and false color in the image. Just for example, let's assume there was an extremely fine white line across the image.

WebIn this lesson you will learn why aliasing occurs when sampling a signal. Aliasing is when a continuous-time sinusoid appears as a discrete-time sinusoid with multiple frequencies. The sampling theorem establishes conditions that prevent aliasing so that a continuous-time signal can be uniquely reconstructed from its samples.

Aliasing is … WebAnti-aliasing filter, a filter used before a signal sampler, to restrict the bandwidth of a signal such as in audio applications. Manual anti aliasing, artistic technique done in pixel art …
In signal processing and related disciplines, aliasing is an effect that causes different signals to become indistinguishable (or aliases of one another) when sampled. It also often refers to the distortion or artifact that results when a signal reconstructed from samples is different from the original continuous signal. Aliasing … See more When a digital image is viewed, a reconstruction is performed by a display or printer device, and by the eyes and the brain. If the image data is processed in some way during sampling or reconstruction, the … See more Sometimes aliasing is used intentionally on signals with no low-frequency content, called bandpass signals. Undersampling, which creates low-frequency aliases, can produce the same result, with less effort, as frequency-shifting the signal to lower frequencies before … See more Historically the term aliasing evolved from radio engineering because of the action of superheterodyne receivers. When the receiver shifts multiple signals down to lower frequencies, … See more Audio example The qualitative effects of aliasing can be heard in the following audio demonstration. Six sawtooth waves are played in … See more Actual signals have a finite duration and their frequency content, as defined by the Fourier transform, has no upper bound. Some amount of aliasing always occurs when such functions … See more Sinusoids are an important type of periodic function, because realistic signals are often modeled as the summation of many sinusoids of … See more Aliasing occurs whenever the use of discrete elements to capture or produce a continuous signal causes frequency ambiguity.
