Hi,
I am getting the following output using the above mentioned code:
load('data (1).mat');
scatter(col,row);
figure
plot(col,row);
Coordinates=[col row]; % put the coordinates into a single matrix
dist = pdist2(Coordinates,Coordinates); %calculate the distance between each point in the matrix
N = size(Coordinates,1); % Number of points in the trace line
result = NaN(1,N); %set up the matrix for the loop to order the points to follow the path
result(1) = 1; % first point is first row in data matrix
for ii=2:N % found this on the internet, creates an order for the points to follow the path of the line
dist(:,result(ii-1)) = Inf;
[~, closest_idx] = min(dist(result(ii-1),:));
result(ii) = closest_idx;
end
Coordinates=Coordinates(result,:); %apply that order to the coordinate list
figure
Hi scatter(Coordinates(:,1),Coordinates(:,2));
figure
plot(Coordinates(:,1),Coordinates(:,2));
- Could you please elaborate what you exactly mean by "adding some some extra line to the end".
Extra line at the initial point is because algorithm expects the initial point to be accurate.
Workaround: Add a point (21,258) in the data set.
Output:
