In each case, the cost to the Kremlin of allowing private media was greater thanbefore.Future work might use our framework to explore other elements of government control ofthe media. In many countries, for example, the media are owned by individuals close to thegovernment rather than by the state directly.
Updated February 20, 2017. Definition: A gradient, or graduated fill, is a color fill that gradually blends from one color to another. A gradient can contain more than two colors, all fading smoothly from one to another. Gradients are very useful for creating shading for three-dimensional and metallic effects.
The magnitude of the gradient tells us how quickly the image is changing, while the direction of the gradient tells us the direction in which the image is changing most rapidly. To illustrate this, think of an image as like a terrain, in which at each point we are given a height, rather than an intensity.e will see that the gradient allows us to answer this question. Letâs consider how the image changes as we move from position (x,y) by a small amount, â, in an arbitrary direction Î¸, which will take us to the position (x+ â cos Î¸, y + â sin Î¸). At (x,y) the image intensity is I(x,y) .
