Abstract
A graphical imaging system, wherein the rough location, size and shape of objects in the image is summarized by a first characteristic descriptor, representing a parametric "pose" computed for each object. A second characteristic descriptor, i.e. a "gesture matching" function, is provided in order to select the single object, or else the set of objects, that best comports with the user's selection gesture. When most closely matched, these key characteristic descriptors permit simple and natural user gestures to distinguish among a large set of graphic objects that may overlap both spatially. User gestures can be simple slashes passing through the object, or quick, coarse approximations of objects' shapes.
