See the hand landmark applications in Dirk's File Exchange: https://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A29180

because I can't figure out what rules you used to draw the cross and the arc.

The cross is nothing but the centroid that I have marked only. In case of drawing an arc we can apply any rules but have to scan the arc and store it's pixel values
