Abstract: A system and method that is able to recognize a user's natural drawing of geometric shapes. The system and method is able to process single-stroke and multi-stroke geometric shapes. It can also apply implicit and user defined constraints to the geometric shapes. The system and method applies these constraints at the vector component level rather than the primitive level. It does this by breaking down both the geometric shapes and constraints on a vector component level. This allows the system and method to handle a larger number of geometric shapes and constraints. After applying the constraints to the geometric shapes at the vector component level, the system and method outputs smooth geometric shapes that incorporated both the implicit and user defined constraints.

Abstract: Disclosed are music symbol recognition apparatuses and methods that recognise music symbols from handwritten music notations. Various implementations may process handwritten music notations by segmenting the handwritten music notations into a plurality of elementary ink segments and then grouping the segments into graphical objects based on spatial relationships between the segments. One or more candidate music symbols may be determined for each graphical object, along with a symbol cost for each symbol, which represents a likelihood that the graphical object belongs to a predetermined class of symbols. The music symbol candidates may be parsed to form graphs based on grammar rules, and the graph most likely to represent the handwritten music notations may be selected for display or other use. The selection may be based on the symbol costs associated with each candidate and on spatial costs associated with the grammar rules that are applied to the candidates.
