Abstract:
A method for recognizing small-font sized text including receiving digital media of a natural scene, the digital media having at least one frame that includes the small-font sized text; generating input maps having values that reflect local properties of corresponding regions in the at least one frame; and detecting regions of the at least one frame that contain the small-font sized text by integrating information from the input maps. The integrated information may include information located between border lines having active pixels therebetween and gaps having a high ratio of non-ink pixels located below a bottom border line and above a top border line in relation to a dominant direction of the text. The active pixels may be pixels having dense changes in character stroke directions.
