Seventh International Conference on Document Analysis and Recognition (ICDAR'03) - Volume 2 Video text recognition using feature compensation as category-dependent feature extraction Edinburgh, Scotland August 03-August 06 ISBN: 0-7695-1960-1
When recognizing multiple fonts, geometric features, such as the directional information of strokes, are generally robust against deformation but are weak against degradation. This paper describes a category-dependent feature extraction method that uses a feature compensation technique to overcome this weakness. Our proposed method estimates the degree of degradation of an input pattern by comparing the input pattern and the template of each category. This estimation enables us to compensate the degradation in feature values. We apply the proposed method to the recognition of video text suffering from degradation and deformation. Recognition experiments using characters extracted from videos show that the proposed method is superior to the conventional alternatives in resisting degradation.
