A background remover is a tool or software that is designed to automatically or manually remove the background of an image or video, isolating the subject or object in the foreground. This process involves selecting the pixels that make up the background and then either deleting them, replacing them with a transparent layer, or replacing them with a new background. The goal of a background remover is to make it easier to use the subject or object in a different context or to enhance the visual appeal of the image or video by removing distracting elements.
