017 - Three Main Concerns in Sketch Recognition

Summary:

In this paper Mahoney and Fromherz describe what they call the three main concerns and then show a system that vaguely covers the three concerns. The three concerns are dealing with human inaccuracy in sketches, being interactive, and being able to add new features later. The system described deals with "stick figure finding". It searches through the sketch checking every single line for different labels. For example, a body has 5 attached lines - a head, 2 arms, and 2 legs. Using an algorithm, the system goes through each line and checks to see if it is a body, and eventually finds the optimal solution. This allows for context lines not to be included in the figure and be seperated.

Discussion:

Two words: NO RESULTS. This algorithm sounds TERRIBLY slow, even though the algorithm is presented in another paper. It seems this paper is totally misnamed, because it has very little to do with the three "main concerns" of sketch recognition past the Introduction. The algorithm behind the system may be interesting, but the paper itself is really just a bunch of filler and icing on top of that algorithm.
