Extracting

A widely used technique is extraction. By this technique a part of the image, normally the foreground, such as a person, is isolated from the rest of the image and put on a new background. Alternatively both background and the extracted foreground can be manipulated and put back together as shown on the example. To make the extraction a line must be drawn around the foreground figure to select it. Several tools can be used for this process such as the lasso tool; however, in this case the filter-extraction tool has been used. The latter is normally the preferred tool for extracting figures with hair or fur.[
