cvGetPixel In OpenCV

void process(void* img) {

IplImage* image = reinterpret_cast(img);

int nl= image->height;
int nc= image->width * image->nChannels;
int step= image->widthStep; // because of alignment

// because imageData is a signed char*
unsigned char *data=
reinterpret_cast(image->imageData);

for (int i=0; i {
for (int j=0; jnChannels)
{

// 3 channels per pixel

if (data[j+1] > data[j] && data[j+1] > data[j+2])
{

data[j]= 0xFF; // 255
data[j+1]= 0xFF;
data[j+2]= 0xFF;

}
}

data+= step; // next line
}
}
