What Is Aliasing and How Does It Relate to Digital Photography?
- https://shuttermuse.com/glossary/aliasing/
- In photography aliasing is a form of distortion that occurs when two elements of the signal being processed to form a digital image become indistinguishable from one another. Aliasing often appears in an image in the form of moiré or false colouring. Many digital cameras feature a built in ‘anti-aliasing filter’ to counteract the effects of aliasing by preventing high frequencies of …

- This is how pixels work to create shapes in an image. The Basics About Aliasing When you look at your image and see the pixels that make up the edges of round or diagonal lines this is aliasing. When you see this pixels drawn rigidly and in only one color, the …

- Sometimes called moiré or a glitch, aliasing is a phenomenon where a digital camera has trouble translating an intricate pattern. Aliasing can result in a number of odd visual artifacts in photos or videos. For example, a person’s finely striped or patterned shirt can cause strange waves or swirl patterns to appear over it in a digital image.

- What is Aliasing and its role in Digital Photography In the signal processing aliasing occurs when we try digitizing the analog signals. As in case of Digital Photography, the photons are to be captured by a digital image sensor and later to be processed by the in house image processor built within the digital camera, Aliasing also appears in case of Digital …
What is Aliasing? - Definition from Techopedia

- Aliasing is an effect that causes different signals to become indistinguishable from each other during sampling. Aliasing is characterized by the altering of output compared to the original signal because resampling or interpolation resulted in a lower resolution in images, a slower frame rate in terms of video or a lower wave resolution in audio.

- Aliasing is characterised by "jagged" diagonal lines. If you try to draw a diagonal line on a pixelated image where each pixel can be only either black or white it will appear stepped or jagged, as in this very bad example: So if you have hard edge in a digital image you will get this effect regardless of the number of colours used.
About Digital Images: Aliasing and Anti-aliasing
- https://courses.washington.edu/arch481/1.Tapestry%20Reader/7.Glossary/1.A-C/alAliasing/
- The term aliasing describes a phenomenon related to measuring recurrent events like radio signals or sound. Your coo-coo clock may have a bird which pops out every hour on the hour, but if you pay attention (called "sampling") every 45 minutes, you might think it pops out only once every 3 hours. The resulting ambiguity or difference between "truth" and "appearance" is …

- All the pixels in a digital image have a square form. For this reason if you zoom in on areas where there are diagonal lines or circles, you will observe that they have a jagged appearance. This is the aliasing or steps effect. Here you can see an example: Aliasing The anti-aliasing algorithms makes this kind of edges look much smoother.

- Aliasing. Digital sampling of any signal, whether sound, digital photographs, or other, can result in apparent signals at frequencies well below anything present in the original. Aliasing occurs when a signal is sampled at a less than twice the highest frequency present in the signal. If an audio signal of containing a ultrasonic 45 kHz tone is sampled at 44.75 kHz, the resulting …

- Aliasing and image enhancement. Digital sampling of any signal, whether sound, digital photographs, or other, can result in apparent signals at frequencies well below anything present in the original. Aliasing occurs when a signal is sampled at a less than twice the highest frequency present in the signal. Signals at frequencies above half the sampling rate must be filtered out …
