For example, in the first data set used for this lab we wanted to isolate the truck from the rest of the image. Using image annotation we are able to remove the pavement and other parts of the image to leave just the truck. At what phase in the processing is this performed? Image annotation is performed after the first step, Initial Processing, has been completed, but before the second step has been completed. What types of Image Annotation are there? There are three types of image annotation: Mask, Global Mask, and Carve. Mask annotation would be used for removing an obstacle that appears in a few images, such as scaffolding or tree branches.
