Opening removes small objects from the foreground (usually taken as the bright pixels) of an image, placing them in the background, while closing removes small holes in the foreground, changing small islands of background into foreground. These techniques can also be used to find specific shapes in an image.
One would mask everything above the store's roof, and the other would mask everything below it. By using these masks/mattes when copying these images onto the third, the images can be combined without creating ghostly double-exposures. In film, this is an example of a static matte, where the shape of the mask does not change from frame to frame ...
As the layer mask can be both edited and moved around independently of both the background layer and the layer it applies to, it gives the user the ability to test a lot of different combinations of overlay. This picture consists of a blue background and on top of that a layer of conifers cut using a layer-mask in the shape of a seagull.
A color spectrum image with an alpha channel that falls off to zero at its base, where it is blended with the background color.. 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. [1]
In image processing, a kernel, convolution matrix, or mask is a small matrix used for blurring, sharpening, embossing, edge detection, and more. This is accomplished by doing a convolution between the kernel and an image .
Example of dilation on a grayscale image using a 5x5 flat structuring element. The top figure demonstrates the application of the structuring element window to the individual pixels of the original image. The bottom figure shows the resulting dilated image. It is common to use flat structuring elements in morphological applications.

In this example a background image, a sprite, and a 1-bit mask are used. As the mask is 1-bit, there is no possibility for partial transparency via alpha blending . A loop that examines each bit in the mask and copies the pixel from the sprite only if the mask is set will be much slower than hardware that can apply exactly the same operation to ...
