Hi thanks for the recommended solution. Would a “geometric solution” be acceptable as well as simpler? I basically find the leftmost, rightmost, lower-most, higher-most pixel coordinates of the blob in the image plane and calculate the rectangular center from this virtual bounding box. Assuming a relatively symmetrical blob which I am using. How can I find the coordinates marked with “?”
Pseudo:
Main
{
…
// per found blob
double Pixel_leftmost = ?
double Pixel_rightmost = ?
double Pixel_upmost = ?
double Pixel downmost = ?
double Width_blob = Pixel_rightmost - Pixel_leftmost
double Height_blob = Pixel_downmost - Pixel_upmost // avoid neg quant
double Ctr_x = Width_blob/2
double Ctr_y = Height_blob/2
…
}
