Uses of ImageFilter in net.sourceforge.javaocr.filter

Classes in net.sourceforge.javaocr.filter that implement ImageFilter

class	AbstractIntegralImageFilter
class	AbstractSinglePixelFilter abstract base class for filters operating on single pixels
class	GrayscaleToRGBA transform pixel from grayscale to RGBA (well, actually ARGB)
class	HistogramFilter collect image histogram and perform useful calculations on it
class	IntegralImageFilter computes integral image.
class	LookupTableFilter apply lookup table to image
class	MedianFilter applies median filter to image (pixel is Mx from his surrounding window) result is collected in destination image.
class	NormaliseGrayscaleFilter normalise grayscale pixels linear basing on min/max values
class	RangeFilter gather min and max values from supplied pixels
class	RGBAToGrayscale converts RGBA image to grayscale
class	SauvolaBinarisationFilter Performs local image threshloding with Sauvola algorithm.
class	SquaredIntergalImageFilter like integral image filter, but sum up squares (useful in various calculations)
class	ThresholdFilter perform threshold filtering TODO: do we need to make this via threshold? Yep - 'if' is still faster than lookup in array
