Classes
class	rdf::PixelConnector
	Abstract class PixelConnector. This is the base class for all pixel connecting classes which implement different algorithms for connecting super pixels. More...
class	rdf::DelaunayPixelConnector
	Connects pixels using the Delaunay triangulation. More...
class	rdf::VoronoiPixelConnector
	Connects pixels using the Voronoi diagram. NOTE: this is highly experimental for it creates new pixels instead of connecting the input pixels (if you need this, take a look at the DelaunayPixelConnector). More...
class	rdf::RegionPixelConnector
	Fully connected graph. Super pixels are connected with all other super pixels within a region. More...
class	rdf::TabStopPixelConnector
	Connects tab stops. More...
class	rdf::DBScanPixelConnector
	Connects Pixels using the DBScan. More...
class	rdf::PixelSet
	PixelSet stores and manipulates pixel collections. More...
class	rdf::TextLineSet
class	rdf::TextBlock
	Represents a text block. A single text block has a boundary region and (possibly) a set of super pixels that are geometrically part of the text region. More...
class	rdf::TextBlockSet
	Stores all text blocks. This class is used to group super pixels with respect to layout constrains (e.g. text columns) More...
class	rdf::PixelGraph
	Represents a pixel graph. This class comes in handy if you want to map pixel edges with pixels. More...
class	rdf::DBScanPixel
	DBScan clustering for pixels. More...
