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] It is often useful to render picture elements (pixels) in separate passes or layers and then combine the resulting 2D images into a single, final image called the composite.
Layers can be partially obscured allowing portions of images within a layer to be hidden or shown in a translucent manner within another image. Layers can also be used to combine two or more images into a single digital image. For the purpose of editing, working with layers allows for applying changes to just one specific layer.
The image fusion process is defined as gathering all the important information from multiple images, and their inclusion into fewer images, usually a single one. This single image is more informative and accurate than any single source image, and it consists of all the necessary information. The purpose of image fusion is not only to reduce the ...
Tone mapped high-dynamic-range (HDR) image of St. Kentigern's Church in Blackpool, Lancashire, England. In photography and videography, multi-exposure HDR capture is a technique that creates high dynamic range (HDR) images (or extended dynamic range images) by taking and combining multiple exposures of the same subject matter at different exposures.

Image fusion based on the multi-scale transform is the most commonly used and promising technique. Laplacian pyramid transform, gradient pyramid-based transform, morphological pyramid transform and the premier ones, discrete wavelet transform, shift-invariant wavelet transform (SIDWT), and discrete cosine harmonic wavelet transform (DCHWT) are some examples of image fusion methods based on ...
Other methods for combining images are also called photomontage, such as Victorian "combination printing", the printing of more than one negative on a single piece of printing paper (e.g. O. G. Rejlander, 1857), front-projection and computer montage techniques. Much as a collage is composed of multiple facets, artists also combine montage ...
Free and open-source software portal; CombineZ is free image-processing software package for creating images with extended depth of field.It runs on Microsoft Windows.The current release is CombineZP (CombineZ-Pyramid), successor to CombineZM (CombineZ-Movie) which was based on CombineZ5 (designed for older versions of Windows and is no longer maintained).
