How to change the origin axis of image?

So I have an image 201*181 pixel, I have already plot the axis along the image the result like the pic below. Now I want to chage the origin of axis to the position i mark. Can anyone help me please, i know this is a simple problem but I cant seem to know the right function to do that.

Is it acceptable if just the label is changed, or do you need data cursor and GetPoint to report back in terms of the shifted coordinates ?

I just need to chage the label, the axis is just something I want to show to understand the coordinate system, it not the data invole.

ax = gca;
set(ax, 'YTickLabel', get(ax, 'YTick') - 100 )
