Hi everyone, I have a image which name is Image1, then I used the contour function with contour(double(Image1)); after which I get a 2-D contour plot. Then is it feasible if I want to get the level values of the contour plot with x coordinate from ,say 100 to 200 when corresponding y coordinate from 100 to 200. Breifly speaking, is it feasible that I want to get the level values of that 10000 points from contour plot(100*100). If so, how? Thanks

I just used a photo as image, then turn it into black-white mode for the contour, the level values on the plot is dependent on the pixel value of the photo.

Now I consider to draw a grid on the contour plot and get the values of grid points.

Read the documentation of contour..there is option of getting level values fromt he function.
[M,c] = contour(X,Y,Z) ;
