Load an existing image mask into the Image Segmenter. When you first load an image into the Image Segmenter, and before you start defining objects, the Image Segmenter enables the Load Mask option. You can load an existing segmentation mask image into the Image Segmenter and refine the segmentation using tools in the refine Refine Mask toolbar group. The segmentation mask image must be a logical image the same size as the image you are segmenting.
For example, you might have previously created a mask of an RGB image in the Color Thresholder and you want to refine the segmentation. Bring the RGB image into the Image Segmenter and then load the mask image. You can then use the tools available in the Image Segmenter to refine the mask.
