Using particle filters for partial sketch matching

In this paper, we focus on an area of sketch recognition that is not much studied, partial sketch matching. Partial sketch recognition refers to the idea of classifying a partial symbol before the user fully completes it. Partial sketch matching will be used to realize the idea of partial sketch recognition. Partial sketch recognition can be used to give feedback to the user during sketching and thus sketching throughput can be increased in a natural manner. We propose an algorithm that is based on particle filters to solve the partial sketch matching problem.
