2. Alpha compositing - Wikipedia

   en.wikipedia.org/wiki/Alpha_compositing

   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]

3. Transparency (graphic) - Wikipedia

   en.wikipedia.org/wiki/Transparency_(graphic)

   The edges of characters and other images with transparent background should not have shades of gray: these are normally used for intermediate colors between the color of the letter/image and that of the background, typically shades of gray being intermediate between a black letter and a white background. However, with, for example, a red ...

4. Channel (digital image) - Wikipedia

   en.wikipedia.org/wiki/Channel_(digital_image)

   Bluescreen technology involves filming actors in front of a primary color background, then setting that color to transparent, and compositing it with a background. The GIF and PNG image formats use alpha channels on the World Wide Web to merge images on web pages so that they appear to have an arbitrary shape even on a non-uniform background.

5. RGBA color model - Wikipedia

   en.wikipedia.org/wiki/RGBA_color_model

   In computer graphics, pixels encoding the RGBA color space information must be stored in computer memory (or in files on disk). In most cases four equal-sized pieces of adjacent memory are used, one for each channel, and a 0 in a channel indicates black color or transparent alpha, while all-1 bits indicates white or fully opaque alpha.

6. Image file format - Wikipedia

   en.wikipedia.org/wiki/Image_file_format

   The PNG file format supports 8-bit (256 colors) paletted images (with optional transparency for all palette colors) and 24-bit truecolor (16 million colors) or 48-bit truecolor with and without alpha channel – while GIF supports only 8-bit palettes with a single transparent color.

7. Image color transfer - Wikipedia

   en.wikipedia.org/wiki/Image_color_transfer

   The image modification process is sometimes called color transfer or, when grayscale images are involved, brightness transfer function (BTF); it may also be called photometric camera calibration or radiometric camera calibration. The term image color transfer is a bit of a misnomer since most common algorithms transfer both color and shading ...
