clear
I = imread('star.png');
[r,c,nc] = size(I);
GC = I(:,:,2);
BI = GC < 200;
[y,x]=find(BI);
y=y*-1; x=x*-1;
c = linspace(1,10,length(x));
figure
plot(x,y,'.')
The code plots the folowing graph
I want to make on continuous line that produces the same image. So basically x an y cordinates for a line that traces this star.
EDIT: Also wanted to mention that I have tried implementing a polyfit--> polyval rountine but It has not given me the desired results.

Your code doesn't run to completion:
I = imread('star.png');
[r,c,nc] = size(I);
GC = I(:,:,2);
BI = GC < 200;
[y,x]=find(BI);
y=y*-1; x=x*-1;
c = linspace(1,10,length(x));
figure
plot(x,y,'.')
