finding x and y coordinates of the image and spline fit
显示 更早的评论
I have binary image 'sceleton.tif' (black line and white background) How can I find x and y coordinates for pixels to make spline fit of the image?
Im=imread('sceleton.tif')

if your boundary is black on the binary image, you can try the following:
[a,b]= find(Im==0);

What do you mean by spline fit? Spline fit of what? The skeleton is continuous so there's nothing to interpolate, unless for some reason you want sub pixel resolution but that wouldn't make sense since the skeletonization was done with pixel resolution.
You have to define the coordinate system then decide which points you want to use for interpolation. Why are you after an equation as opposed to just the (x,y) coordinates?
