19. A system, comprising a component that directs stroke width based text detection of text in a captured image of a scene, the component including: a stroke width transform generator that generates a representation of the captured image, the representation including pixels that are associated with stroke widths of components of the captured image; identifying connected components of the captured image by filtering out portions of the pixels using metrics related to stroke width to exclude the portions of the pixels; and a text identifier that detects detecting text in the captured image by building a graph that contains nodes that represent identified connected components, wherein, initially, the graph is an intact string of nodes in which each node is connected to all other nodes, and wherein connections between nodes that are identified as not belonging to a same text line are severed, based on: distance in a vertical direction; an amount of intersection in a horizontal direction; and a difference in average stroke width between connected components.
20. The system of claim 19 , wherein every text line is presumed to be horizontal, and wherein connected components in a same text line have similar average stroke width values.
