Compacting oriental fonts by optimizing parametric elements

The ideographic, oriental alphabets have many more symbols and are more complex than Western alphabets. Composing glyphs from radicals and radicals from strokes can simplify their digital representation. We compact existing outline-based oriental fonts and preserve original design with a parametric representation. Our method comprises: classification of elements to groups, parameterization of representative elements, optimization of the parametric representatives to match all group elements, and compaction using quantization. We introduce automatic classification and optimization using topological signature mapping between element shapes. We control the trade-off between compacting and preserving quality simply and naturally by using quantization in parametric space.
