Abstract
Traditional optical character recognition (OCR) uses thresholding and pre- defined characters to recognize text. This study makes the assumption that thresholding can cause loss of potentially valuable information. A more ver- satile approach to character recognition with minimal thresholding is offered which relies on a max-tree and image moments. The max-tree is a tree repre- sentation of the image where each level represents a grey-level and each node contains attributes. The image moments are scale and translational invariant, this allows recognition of a wide range of characters instances. Finally super- vised learning is used to classify the characters, and line and word segmentation is used to obtain a full textual reconstruction of an input image.
