The random walker algorithm is an algorithm for image segmentation. In the first description of the algorithm, [ 1 ] a user interactively labels a small number of pixels with known labels (called seeds), e.g., "object" and "background".
On Wikipedia and other sites running on MediaWiki, Special:Random can be used to access a random article in the main namespace; this feature is useful as a tool to generate a random article. Depending on your browser, it's also possible to load a random page using a keyboard shortcut (in Firefox , Edge , and Chrome Alt-Shift + X ).
However, without the other component, a component image reveals no information about the original image; it is indistinguishable from a random pattern of / pairs. Moreover, if you have one component image, you can use the shading rules above to produce a counterfeit component image that combines with it to produce any image at all.
Lavarand, also known as the Wall of Entropy, is a hardware random number generator designed by Silicon Graphics that worked by taking pictures of the patterns made by the floating material in lava lamps, extracting random data from the pictures alledgedly using the result to seed a pseudorandom number generator.
The 256 available colors would be used to generate a dithered approximation of the original image. Without dithering, the colors in the original image would be quantized to the closest available color, resulting in a displayed image that is a poor representation of the original. The very earliest uses were to reduce images to 1-bit black and white.
A single image random text ASCII stereogram is an alternative to SIRDS using random ASCII text instead of dots to produce a 3D form of ASCII art. Map textured stereogram In a map textured stereogram, "a fitted texture is mapped onto the depth image and repeated a number of times" resulting in a pattern where the resulting 3D image is often ...
The process used to develop the first random-dot stereogram is illustrated below. 1. Create an image of suitable size. Fill it with random dots. Duplicate the image. 2. Select a region in one image, in this case, in the right image. 3. Shift this region horizontally by one or two dot diameters and fill in the empty region with new random dots.
Different models can be generated by changing both deterministic parameters and a random seed. In computing , procedural generation is a method of creating data algorithmically as opposed to manually, typically through a combination of human-generated content and algorithms coupled with computer-generated randomness and processing power.
