Beschreibungen/Notizen

• Identification of mathematical expressions in document images is attempted. Several features starting from low level image features, shape features, linguistics information, etc. are extracted and combined to pinpoint the expressions. A performance index has been formulated to evaluate the identification results. Experiment uses a data set of 200 publicly available images containing 1163 embedded and 1039 displayed expressions. Test results show accuracies of 88.3% and 97.2%, respectively for extracting embedded and displayed expressions perfectly.
