a) A set of rules or processes for solving a problem in a finite number of steps. In audio, video, and data coding, the step-by-step procedure (often including repetition) which provides suitable compression and/or encryption for the specific application. When used for compression, this mathematical process results in a significant reduction in the number of bits required for transmission and may be either lossless or lossy.
b) Step-by-step procedure for the solution to a problem. First the problem is stated and then an algorithm is devised for its solution.

The alpha channel is used to specify an alpha value for each color pixel. The alpha value is used to control the blending, on a pixel-by-pixel basis, of two images. Alpha typically has a normalized value of 0 to 1. In a computer environment, the alpha values can be stored in additional bit planes of frame-buffer memory. When you hear about 32-bit frame buffers, what this really means is that there are 24 bits of color, 8 each for red, green, and blue, along with an 8-bit alpha channel. Also see Alpha Mix.
: new pixel = (alpha) (pixel A color) + 1 – alpha (pixel B color)
