| Abstract | ||||
| Digital technologies have provided many capabilities that serve the field of graphic for both still and moving images, whether cinematic or television, among the effects that were commonly used before digital technology is the technique of changing image backgrounds, where photography was done using a black background so that the background is transparent on the image Film negative, a , it has made it easier to perform this effect in a much simpler and much easier way. Photography is done on a blue or green background for the foreground image and then combines the two images immediately after excluding the blue or green background color from it. This technique is called chroma, and the viewer at the beginning of the use of this effect accepted this inaccurate merging or composition of the two images, but the progress In high-definition image sciences, which reached (6K), which required that the effect should be used in an optimal way that does not represent any degree of mental confusion for the viewer, or affect his conviction of the credibility of the image, and this study represents a step in the way to perfectly adjust the effect by controlling the color of exclusion the user. | ||||
