How to display axis on the image ?

Hello,

I have a question how to display visible arbitrary axis on the image when I plot something on the image ? Like here :

I would appreciate for any help please :)

You want a normal axis? or like the one shown in image?

[agatte]

like normal axis shown on the image or it could be also like on this image

The axes shown there appear to just be arbitrarily orientated. Unless you aren't referring to those axes.

[agatte]

yes, I know that they are arbitrary oriented. But I dont know exactly how to display arbitrary oriented axes ?

[Adam]

I don't think you can in normal Matlab. Maybe something in the file exchange can do this.

Normal axis

imshow('yourimage') ;
axis on

As shown on image

imshow('image.png')

pts = [     4    67
   142    12
   137     3
   176   107];

hold on

plot(pts(1:2,1),pts(1:2,2),'r') ;
plot(pts(3:4,1),pts(3:4,2),'r') ;
