How to add an image to the current axes without replacing existing plots

I have created a matrix, called "Final" and I want to plot its contour pattern on an image, in a polygon shape.

I tried "imagesc(Final,"XData",[min_x_2 max_x_2],"YData",[min_y_2 max_y_2],"AlphaData",0.5)" and was able to plot a rectangle contour map successfully. But I want to plot it on a RoI such as [1558,1798; 1790,1806; 1782,2006; 1562,2018].

(Note that the "Final" matrix's contour map might exceed the area of the polygon)

Thank you.

You can use hold

fcontour(@(x,y) (x-50).^2+(y-50).^2,[20,80],'m'); hold on

imshow(imread('cameraman.tif')); hold off

h=gca; h.Children=flip(h.Children);
