Filter Forge also includes rendering options such as anti-aliasing, bump maps and normal maps, environment mapping, ambient occlusion, seamless tiling, and a text-based batch renderer. Users can randomize or control specific parameters of each filter through sliders, color pickers, and checkboxes. Sets of parameter values can be saved as presets.
A compression artifact (or artefact) is a noticeable distortion of media (including images, audio, and video) caused by the application of lossy compression. Lossy data compression involves discarding some of the media's data so that it becomes small enough to be stored within the desired disk space or transmitted ( streamed ) within the ...

In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...
The technique of anamorphic projection can be seen quite commonly on text written at a very flat angle on roadways, such as "Bus Lane" or "Children Crossing", to make it easily read by drivers who otherwise would have difficulty reading obliquely as the vehicle approaches the text; when the vehicle is nearly above the text, its true abnormally ...
ExifTool is a free and open-source software program for reading, writing, and manipulating image, audio, video, and PDF metadata.As such, ExifTool classes as a tag editor.It is platform independent, available as both a Perl library (Image::ExifTool) and a command-line application.
Animated example of what a glitched video can look like, by Michael Betancourt (Mae Murray in a screen test). Glitch art is an art movement centering around the practice of using digital or analog errors, more so glitches, for aesthetic purposes by either corrupting digital data or physically manipulating electronic devices.
The PQM quantifies the distortion in the luminance, and contrast distortion using an approximation (variances) weighted by the mean of each pixel block to obtain the distortion in an image. This distortion is subtracted from 1 to obtain the objective quality score.
