Eric Saund, David Fleet, Daniel Larner, and James MahoneySummary
Presented in this paper is an image editing program called ScanScribe. ScanScribe provides special functionality for selecting and structuring groups. Grouping is represented by a lattice structure where an image object can belong to more than one group. ScanScribe has an image analysis technique for seperating foreground and background. ScanScribe uses auomatic structure recognition to group elements of an image. The group recognition is based on Gestalt laws of human visual perception. No formal evaluation was conducted, but a number of users reported that the system was easy to learn to use.
Discussion
Our ability as humans to easily differentiate text from shape and form groupings of these different objects seems a valuable place to begin investigating for methods to employ with machines. I really like the idea of using laws of perception as a basis for building mathematical calcualtions of similarity. However, the human eye and mind do not function the same way as a computer; therefore, these laws of perception may not translate as easily to machines. As well, other factors, such as domain and contextual knowledge, play a role in our ability to differentiate shape from text.
