Outline Filter

The Outline filter is used to outline edges present within the image. Similar to an outline convolution filter this filter reacts to changes in intensity or color across edges. Sharper edges will result in higher intensity values. The outline function uses a convolution filter size based on the user specified window size. Results are then normalized and displayed as grayscale values.
