Projects
EvaLTex (Evaluating Text Localization) is a unified evaluation framework used to measure the performance of text detection and text segmentation algorithms. It takes as input text objects represented either by rectangle coordinates or by irregular masks. The output consists of a set of scores, at local and global levels, and a visual representation of the behavior of the analysed algorithm through quality histograms.
