Detailed Description

Class for performing the Otsu Thresholding algorithm.

The Otsu algorithm performs black and white image segmentation using a dynamic threshold value.

The threshold value is obtained by analysising the histogram of the grey values of the image pixels. The threshold value is calculated as being the dip inbetween to the two highest peaks.

void AROtsuThresholding::ProcessImage (  ARImage *  image, int  offset = 0, bool  useLuminance = true )

Performs Otsu Thresholding against the passed image. The alpha channel will be converted to 'pure' black and white based on the dynamic threshold value. Parameters: image  Pointer to the image to process. offset  An optional amount to offset the dynamic threshold by. useLuminance  Denotes whether to use luminance formula for calculating the black and white values or to use an average of the red, green and blue components.
