Abstract: The following generally relates to pre-processing signature data. In some examples, the extracted signature data may be used to train a signature classification model configured to identify a signature type for an input signature. As part of the pre-processing, the techniques disclosed herein relate to extracting the signature data from a corpus of signed documents. For example, techniques disclosed herein may use anchor points to define a boundary box. Additionally, the pre-processing may include aligning the image data of the signatures, for example, by correcting a skew. The extracted and aligned signatures may be used to train the signature classification model.
