Jaggies

Jaggies
By Vincent Bockaert
Hardly a technical term, jaggies refer to the visible "steps" of diagonal lines or edges in a digital image. Also referred to as "aliasing", these steps are simply a consequence of the regular, square layout of a pixel.

Enlarging a digital image or examining it from close by will reveal visible steps in diagonal lines in an image.

A slang term used to describe the jagged edges created by pixels.

Jaggies
This is the jargon or informal name for digital artifacts found in raster images. These star-line lines appear where there should be a smooth straight line or curve.

Jaggies
The term to describe diagonal lines in a digital image that appear jagged. Jaggies are produced due to the square nature of a pixel. Even when aliased certain subjects like telephone lines seem unnatural.

jaggies
(1) slight noticeable unwanted angles that are apparent on a cut line or curve that would otherwise be smooth; (2) an effect caused by images or lines being rendered at too low a resolution that makes edges rough or stair-stepped.

Jaggies - the not-so-technical term for visible steps along lines or edges in a digital image. This is also known as 'aliasing'.

Jaggies: The stair-stepping effect that can be seen in curves and diagonal lines when a picture's resolution is too low and individual pixels begin to show in the image.

Jaggies - The stair-like appearance of diagonal lines.
JPEG - Stands for Joint Photographic Experts Group. Along with GIFs, the JPEG file format is one of the main graphic formats displayed on the web.

Jaggies
The jagged stair-stepping effect often seen in images whose resolutions are so low that individual pixels are visible.
JPEG (Joint Photographic Experts Group)
A technique for compressing full-color bit-mapped graphics.

Also known as aliasing or staircasing, these refer to the stepped effect observed along a diagonal line of square pixels.

Jaggies. Staircasing effect of lines that are not perfectly horizontal or vertical, caused by pixels that are too large to represent the line accurately. See also anti-aliasing.

Jaggies - Slang term for a low resolution digital image that contains sharp (jagged) curves, caused by the use of fewer, larger pixels.

Something called anti-aliasing now comes into play during the interpolation that helps suppress the jaggies. A look back at Figure 3 shows that the jaggies are most noticeable where light pixels border dark pixels.

The problem with in-camera sharpening is that it increases the visibility of jaggies and can increase the visibility of other image artifacts.

Antialiasing is the process of reversing an alias, that is, reducing the 'jaggies'. Antialiasing produces smoother curves by adjusting the boundary between the background and the pixel region that is being antialiased.

Since demosaicing is not required to produce a full-color image, the color artifacts ("colored jaggies") associated with that process are not seen. Thus, the image-softening anti-aliasing required to mitigate those artifacts is not required.

This reduced some of the jaggies that were noticeable on the original but still was a reasonable file size for upload on my 56K modem (10MB). From my experiments, using GF yielded a very slight quality improvement over bicubic for this image.

2. Digital sensors have low pass filters to reduce "jaggies" which is compensated for by sharpening after the fact.
Again, scanners don't do this. They will only add sharpening if you ask for it in the scanning software.

This is essentially useless for photographic work as it is almost sure to result in artificial computer-like jagged edges or "jaggies.

Surprisingly, scanning line art requires relatively high resolutions to achieve good results. If you scan under 1200 dpi, your results may not be smooth and sharp. Jagged edges or "jaggies" are the most common problem that occurs from line art ...

Third, most digital cameras contain optical filters situated between the lens and the image sensor which smooth out the jaggies optically before it's recorded by the sensor.

but also raised memory or disk storage requirements, longer processing times and slower transmission over networks. Too few pixels (or too shallow colour depth) can result in the pixels becoming noticeable in an image, which can show "jaggies" - ...
