Color and grayscale: As discussed above, we can easily extract color and grayscale channels from an image. Note that color channels could be RGB, LUV or HSV. LUV color channels have shown to be most informative among all color spaces. Linear filters: This is a simple method for generating channels.
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.
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 ...
New software, techniques and cloud services now makes it possible to extract the songs played on the radio and digitally save them on separate audio tracks. Available techniques make it possible to rip the music from Internet radio broadcasts, satellite radio broadcasts and FM radio broadcasts. Ripping is more than simply recording the audio.
A color spectrum image with an alpha channel that falls off to zero at its base, where it is blended with the background color.. In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1]

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.
