Abstract
A processing device may parse a group of strokes representing a mathematical expression. The group of strokes may be examined to determine whether the group of strokes satisfies any of a finite set of rules. When the group of strokes, included in a region, satisfies any of the finite set of rules, the region may be partitioned according to a satisfied one of the finite set of rules. The group of strokes included in the region may be further examined to determine whether the group of strokes may be further partitioned according to any of the finite set of rules. After all regions have been examined and no further partitioning of regions may be performed, all mathematical symbols of the mathematical expression may be isolated in at least some of the regions and may be recognized.
