Image Segmentation using Salient Points-Based Object Templates

Using prior knowledge about object(s) is beneficial for accurate image segmentation. We present an image segmentation method that performs segmentation using a set of user provided object templates. We call the salient points of the object template that are within the object, the characteristic points of the object. Given an arbitrary image, each object templated can be mapped onto the image as a bit mask by using the correspondence between the salient points of the image and the characteristic points of the object template. To segment a desired object o in an image, the bit masks obtained using all templates for o are combined. Experiments show that this method can create good segmentations.
