Lasso Tool
The lasso (or "free form selection") is an editing tool available, with minor variations, in most digital image editing software and some specific strategy games. It is often accessed from the standard main menu (in Photoshop, Paint Tool SAI, and GIMP, as common examples), by clicking the icon of a dotted line shaped like a rope lasso, from which the common name arises. Standard operation The lasso tool operates on the active layer of an image, and is used by clicking and dragging to trace the edges of a selection. Most software supports multiple closed contours, which can be selected by crossing over the edge path multiple times. It is also typically not necessary to close the shape: releasing the mouse button triggers the software to close any open loop(s) automatically. The area enclosed by the cursor path will remain selected and open to various transform operators (shift, scale, cut, copy, and paste, for example) until elsewhere in the image is clicked. At this point, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graphics Software
In computer graphics, graphics software refers to a program or collection of programs that enable a person to manipulate images or models visually on a computer. Computer graphics can be classified into two distinct categories: raster graphics and vector graphics, with further 2D and 3D variants. Many graphics programs focus exclusively on either vector or raster graphics, but there are a few that operate on both. It is simple to convert from vector graphics to raster graphics, but going the other way is harder. Some software attempts to do this. In addition to static graphics, there are animation and video editing software. Different types of software are often designed to edit different types of graphics such as video, photos, and vector-based drawings. The exact sources of graphics may vary for different tasks, but most can read and write files. Most graphics programs have the ability to import and export one or more graphics file formats, including those formats written fo ...

Strategy Video Game
Strategy video game is a major Video game genres, video game genre that focuses on analyzing and strategizing over direct quick reaction in order to secure success. Although many types of video games can contain strategic elements, the strategy genre is most commonly defined by a primary focus on high-level strategy, logistics and resource management. They are also usually divided into two main sub-categories: Turn-based strategy, turn-based and Real-time strategy, real-time, but there are also many strategy cross/sub-genres that feature additional elements such as tactics, diplomacy, economics and exploration. Typical experience A player must plan a series of actions against one or more opponents, and the reduction of enemy forces is usually a goal. Victory is achieved through superior planning, and the element of chance takes a smaller role. In most strategy video games, the player is given a godlike view of the game world, and indirectly controls game units under their comm ...

Adobe Photoshop
Adobe Photoshop is a raster graphics editor developed and published by Adobe Inc., Adobe for Microsoft Windows, Windows and macOS. It was created in 1987 by Thomas Knoll, Thomas and John Knoll. It is the most used tool for professional digital art, especially in raster graphics editing, and its name has become Generic trademark, genericised as a verb (e.g. "to photoshop an image", "photoshopping", and "photoshop contest") although Adobe disapproves of such use. Photoshop can edit and compose raster images in multiple layers and supports Mask (computing), masks, alpha compositing and several color models. Photoshop uses its own PSD and PSB file formats to support these features. In addition to raster graphics, Photoshop has limited abilities to edit or render text and vector graphics (especially through clipping path for the latter), as well as 3D graphics and video. Its feature set can be expanded by Photoshop plug-in, plug-ins; programs developed and distributed independentl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lasso
A lasso or lazo ( or ), also called reata or la reata in Mexico, and in the United States riata or lariat (from Mexican Spanish lasso for roping cattle), is a loop of rope designed as a restraint to be thrown around a target and tightened when pulled. It is a well-known tool of the Mexican and South American cowboys, which was then adopted from the Mexicans by the cowboys of the United States. The word is also a verb; ''to lasso'' is to throw the loop of rope around something. Etymology The word ''lasso'' seems to have begun to be used as an English word in the early nineteenth century. It may have originated from the Castilian Spanish, Castilian word ''lazo'', which is first attested in the thirteenth century in the sense 'noose, snare', and derives in turn from classical Latin language, Latin ''laqueus'' ('noose, snare, trap, bond, tie'). The rope or lasso used to restrain cattle is also called ''Reata'' or ''La Reata'' in Mexico, which was Anglicized to “Lariat” or “R ...

Pointing Device Gesture
In computing, a pointing device gesture or mouse gesture (or simply gesture) is a way of combining pointing device or finger movements and Point-and-click, clicks that the software recognizes as a specific Event (computing), computer event and responds to accordingly. They can be useful for people who have difficulties typing on a computer keyboard, keyboard. For example, in a web browser, a user can navigate to the previously viewed page by pressing the right pointing device button, moving the pointing device briefly to the left, then releasing the button. History The first pointing device gesture, the "click and drag, drag", was introduced by Apple Inc., Apple to replace a dedicated "move" button on mice shipped with its Macintosh and Lisa computers. Dragging involves holding down a pointing device button while moving the pointing device; the software interprets this as an action distinct from separate clicking and moving behaviors. Unlike most pointing device gestures, it doe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GrabCut
GrabCut is an image segmentation method based on graph cuts. Starting with a user-specified bounding box around the object to be segmented, the algorithm estimates the color distribution of the target object and that of the background using a Gaussian mixture model. This is used to construct a Markov random field over the pixel labels, with an energy function that prefers connected regions having the same label, and running a graph cut based optimization to infer their values. As this estimate is likely to be more accurate than the original, taken from the bounding box, this two-step procedure is repeated until convergence. Estimates can be further corrected by the user by pointing out misclassified regions and rerunning the optimization. The method also corrects the results to preserve edges. There are several open source implementations available including OpenCV (as of version 2.1).{{citation needed, date=March 2021 See also * Connectivity (graph theory) * Prim's algorithm ...

Digital Image Processing
Digital image processing is the use of a digital computer to process digital images through an algorithm. As a subcategory or field of digital signal processing, digital image processing has many advantages over analog image processing. It allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of Noise (signal processing), noise and distortion during processing. Since images are defined over two dimensions (perhaps more), digital image processing may be modeled in the form of Multidimensional system, multidimensional systems. The generation and development of digital image processing are mainly affected by three factors: first, the development of computers; second, the development of mathematics (especially the creation and improvement of discrete mathematics, discrete mathematics theory); and third, the demand for a wide range of applications in environment, agriculture, military, industry and medical science has incre ...

Layers (digital Image Editing)
Layers are used in digital image editing to separate different elements of an image. A layer can be compared to a transparency on which imaging effects or images are applied and placed over or under an image. Today they are an integral feature of image editors. In the early days of computing, memory was at a premium and the idea of using multi-layered images was considered infeasible in personal computer applications as the tradeoffs were image size and color depth. As the price of memory fell it became feasible to apply the concept of layering to raster images. The first software known to apply the concept of layers was LALF, which was released in 1989 for the NEC PC-9801. LALF's terminology for layers is "cells", after the concept of drawing animation frames over-top of a stencil. Layers were introduced in Western markets by Fauve Matisse (later Macromedia xRes), and then available in Adobe Photoshop 3.0, in 1994, which lead to wide-spread adoption. In vector image editors ...

Alpha Compositing
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. 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. Compositing is used extensively in film when combining computer-rendered image elements with live footage. Alpha blending is also used in 2D computer graphics to put rasterized foreground elements over a background. In order to combine the picture elements of the images correctly, it is necessary to keep an associated '' matte'' for each element in addition to its color. This matte layer contains the coverage information—the shape of the geometry being drawn—making it possible to distinguish between parts of the image where something was drawn and parts that are empty. Although the most basic operation of combining two images is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
