Adptive thresholding using the integral Image

Derek Bradley * Gerhard Roth

Pseudocode given by the paper:

void vvAdaptiveThreshold( IplImage* inImg, IplImage* outImg){int S = inImg->width >> 5;int T = 10;char *input, *bin;input = inImg->imageData;bin = outImg->imageData;int width = inImg->width;int height = inImg->height;unsigned long* integralImg = 0;int i, j;long sum=0;int count=0;int index;int x1, y1, x2, y2;int s2 = S/2;//bin = new unsigned char[width*height];// create the integral imageintegralImg = (unsigned long*)malloc(width*height*sizeof(unsigned long*));for (i=0; i<width; i++){// reset this column sumsum = 0;for (j=0; j
