OpenEXR's multi-resolution and arbitrary channel format makes it appealing for compositing, as it alleviates several painful elements of the process. Since it can store arbitrary channels— specular , diffuse, alpha , RGB, normals, and various other types—in one file, it takes away the need to store this information in separate files.
The number of channels depends on whether the image is grayscale or color and whether it has an alpha channel. PNG allows the following combinations of channels, called the color type. A demonstration of the color depth in a PNG file, in bits per channel. Left: 8 bits; Right: 16 bits. Note the artifacts, adjusted contrast for clarity.
This is a list of software palettes used by computers. Systems that use a 4-bit or 8-bit pixel depth can display up to 16 or 256 colors simultaneously. Many personal computers in the early 1990s displayed at most 256 different colors, freely selected by software (either by the user or by a program) from their wider hardware's RGB color palette.
HOG turned out to be the most informative channel compared with rest of the channels. The detection rate of HOG was 89%. Further, among the color channels (RGB, HSV and LUV), LUV had the best detection rate of 55.8%. Grayscale channel was least informative with the detection rate of only 30.7%. Next, they evaluated the performance of various ...
To create single-color areas, the flood fill tool is often the easiest tool. First select an odd color (e.g. pink if there is no pink in the image) and experiment to find the right tolerance setting. Undo each time. Now you pick a main area color (try control-click while flood-fill is activated) and fill by clicking into each contiguous area.
A 32-bit CMYK image (the industry standard as of 2005) is made of four 8-bit channels, one for cyan, one for magenta, one for yellow, and one for key color (typically is black). 64-bit storage for CMYK images (16-bit per channel) is not common, since CMYK is usually device-dependent, whereas RGB is the generic standard for device-independent ...

Most PC based Internet radio ripping software is built for Shoutcast-style of streams as this MP3-based protocol offers the widest selection of Internet radio stations. Such wide selection of music is one of the major advantages for recording songs from Internet radio compared to FM and satellite radio as well as the fact that it works with ...
