  2. Visual masking - Wikipedia

    en.wikipedia.org/wiki/Visual_masking

    Visual masking involves surrounding a target image (here, the word "radio") with another image. Visual masking is a phenomenon of visual perception. It occurs when the visibility of one image, called a target, is reduced by the presence of another image, called a mask. [1] The target might be invisible or appear to have reduced contrast or ...

    en.wikipedia.org/wiki/Visual_cryptography

    A demonstration of visual cryptography. When two same-sized images of apparently random black-and-white pixels are superimposed, the Wikipedia logo appears. In this example, the binary image has been split into two component images. Each component image has a pair of pixels for every pixel in the original image. These pixel pairs are shaded ...

    en.wikipedia.org/wiki/2D_computer_graphics

    2D computer graphics is the computer-based generation of digital images—mostly from two-dimensional models (such as 2D geometric models, text, and digital images) and by techniques specific to them. It may refer to the branch of computer science that comprises such techniques or to the models themselves. Raster graphic sprites (left) and masks

    Dodging lightens an image, while burning darkens it. Dodging the image is the same as burning its negative (and vice versa). Dodge modes: The Screen blend mode inverts both layers, multiplies them, and then inverts that result. The Color Dodge blend mode divides the bottom layer by the inverted top layer. This lightens the bottom layer ...
