Modules
	Camera Image Preprocessing
	Camera Image Preprocessing module exposes the features that allows an integrator to enhance camera images before performing various processing on it.

Classes
class	CBinarize
	The CBinarize class offers image binarization featuresBinarization is the first stage in image recognition. It convert the input image into a black & white image for faster processing. The CBinarize class offers the following image binarization algorithms: More...
class	CBlankImageDetection
	The CBlankImageDetection class offers blank image detection featuresIt contains an implementation of blank image detection algorithm that is able to detect whether a image contains any useful information. The algorithm can work with images obtained from various paper sources, like glaring white, yellow old paper or gray recycled paper. More...
class	CDarkBordersRemoval
	The CDarkBordersRemoval class provides dark borders removal capabilities.It features an algorithm for automatic dark border detection and removal in all types of images: monochrome, grayscale or color. The integrator can also specify threshold under which the border pixels are considered "dark" by the dark border removal algorithm. If not, the algorithm will use the following predefined values for the definition of "dark" borders: More...
class	CDeskew
	The CDeskew class offers deskew image correction.Deskew image correction is normally used for images that were scanned misaligned or photographed from a low angle Deskew/Skew angles are calculated counter-clockwise. More...
class	CDespeckle
	The CDespeckle class provides image noise reduction features via an image despeckle filterIt works only with black and white images. More...
class	CDitherRemoval
	CDitherRemoval attempts to perform the reversal of image dithering, which is a common technique for printing with inkjet printers. Dithering is analogous to the halftone technique used in printing. Due to the fact that during the dithering process a part of the image information is lost, the resulting image after the dithering removal will not be the same as the original. However, the resulting image would improve the recognition rate of iDRS recognition engines (both OCR and barcode). More...
class	CGreyscale
	The CGreyscale class offers image greyscale conversionThis class contains an algorithm for converting color images to greyscale. More...
class	CImageOperation

class	CPunchHoleRemoval
	The CPunchHoleRemoval class is part of iDRS advanced preprocessing module. It provides punch hole removal capabilities. More...
class	CResize
	The CResize class offers image resizing.The class contains an algorithm for image resizing using all types of images: More...
