Automated Oracle Bone Script Analysis: Noise Reduction, Segmentation, and Character Recognition
Let the original rubbing image be represented as $I_{raw}$. The preprocessing stage applies a transformation $T_{prep}$ to yield a cleaned image $I_{clean} = T_{prep}(I_{raw})$. Subsequently, a descriptor extractor $T_{feat}$ maps the cleaned image to a feature vector $\mathbf{v} = T_{feat}(I_{clean...
