Hi, I want to find the x and y coordinates of all the pixels corresponding to the white pixels in this image and store them in an array. Later I want to find the equation of the best fitting curve passing through these coordinates. Can someone please help me with how this can be done?
PS I am very new to MATLAB and programming in general.
Thank you in advance

Ran in:
You will first need to get rid of the horizontal line of white pixels near the top,
load Image
Image(1:20,:)=0; Image=bwpropfilt(Image>0,'ConvexArea',1); %Image cleanup
[y,x]=find(Image); %Get coordinates
plot(x,y,'x')
