%Find minimal Geodesic distance between point two point (x0,y0 and x1,y1) on image (Im) %The image can be color or grayscale %return geodesic distance between x0,y0 and x1,y1
%Use the image as topological map with color as height and use the %Dijkstra's algorithm to find minimal geodesic distance between x1,y1 and x0,y0

%Input:

%Im color image (or other multichannel image)

%x0,y0 coordinates (on the image) of the origin point %x1,y1 Cordinates of the target point

%NumSteps optional parameter that allow you to limit the number of cycle of the calculation this may result faster but less accurate calculation

%WeightDist the distance component have two parts distance travel on %the image plane and distance in the color/grayscale value this parameter %control the relative weight of the distance on the image plane

%Output: %DistMap a map of geodesic distance to coordinate x0,y0

%Method: %Use the image as topological map and use the Dijkstra's algorithm to find geodesic distance
