Abstract
Systems, methods, and applications for detection text in a raster image include converting a raster image into a vector representation of the image, identifying pairs of shapes of similar size and within a predefined distance of one another, forming shape graphs from the identified shape pairs, identifying chains of shapes from the formed shape graphs, determining characteristic chain lines associated with the identified chains of shapes, straightening the identified chains of shapes into a straight line based on the corresponding chain lines associated with the respective identified chains of shapes, and classifying the straightened identified chains as text or non-text using an automatic text classifier.
