My approach to symbol recognition of Chinese numerals uses techniques well established in digital image processing, including black/white conversion, digital binary morphology, pixel histograms for line counting, Zhang-Suen thinning for skeletonization, and other simple techniques such as median filtering.  These techniques are combined to form a feature extraction algorithm.  Once features are identified simple table lookups are preformed for number recognition.  The table is constructed from known features in each of the non-complex and common Chinese numerals.

This project also implements basic image processing algorithms, including point and neighborhood operations.
