Topics studied include the recognition of legal amount, courtesy amount and date.
Segmentation serves as the basis of recognition.
To overcome this problem, a feedback-based approach is proposed. It is implemented in two steps. In the first step, segmentation is done according to the structural features found between the connected components in the legal amount. In the second step, a feedback process is introduced to re-segment the parts that could not be identified in the first step. Subsequently, the classifier is used to verify the re-segmentation result.
