Above the image is my task. In this task yellow rectangle is starting point and cofee color rectangle is end point. So i have to connect the each blob from yellow rectangle and reach the coffee rectangle through white path.
In this task now i have the centroids of the each blob. And i don't know after? how to connect the each blob from yellow reactangle.
My idea is drawing horizontal and vertical line from yellow reactangle centroid through white pixels and if these lines touches another boundry. Then we will connect these blobs centroid.
My doubt is how to draw horizontal and vertical line form one pixel(centroid) and check the color of each pixel in that line?
