Automated methods for consolidating raw sketches into artist-intended curve drawings

A method for converting a raw drawing comprising a plurality of strokes into an artist-intended curve drawing, the method comprising:

• obtaining, at a computer system, a computer representation of a raw drawing, the raw drawing comprising a plurality of strokes, each stroke represented in a vector format in the computer system;
• clustering, by the computer system, the plurality of strokes into one or more clusters, each cluster comprising a corresponding group of one or more strokes;
• for each of the one or more clusters, performing a curve fitting, by the computer system, to thereby determine a computer representation of a corresponding aggregate curve that is fitted to the group of strokes in the cluster;
• and
• generating, by the computer system, a computer representation of an artist-intended curve drawing corresponding to the raw drawing, the artist-intended curve drawing comprising the aggregate curve corresponding to each cluster in place of the group of one or more strokes corresponding to each cluster;
• wherein clustering, by the computer system, the plurality of strokes into one more clusters comprises performing, by the computer system, a plurality of iterative procedures to either group strokes into precursor clusters or to divide precursor clusters into precursor sub-clusters based on one or more models of human perception of raw drawings comprising pluralities of strokes.
