This paper presents a novel image editing program emphasizing easy selection and manipulation of material found in informal, casual documentssuch as sketches, handwrittennotes, whiteboardimages, screensnapshots, and scanneddocuments. The program, called ScanScribe, offers four significant advances. First, it presents a new, intuitive model for maintaining image objects and groups, along with underlyinglogic for updating these in the course of an editing session. Second, ScanScribe takes advantage of newly developed image processing algorithms to separate foreground markings from a white or light background, and thus can automatically render the background transparent so that image material can be rearranged without occlusion by background pixels. Third, ScanScribe introduces new interface techniques for selecting image objects with a pointing device without resorting to a palette of tool modes. Fourth, ScanScribe presents a platform for exploitingimage analysis and recognitionmethods...
