hi, not sure if this is suitable for you, it's a bit rough and low efficiency(low fps), but looks simple, by using MATLAB Function and base line/plot/image build-in method, where the code within "MATLAB Function" is :
function fcn(u)
coder.extrinsic('image')
persistent h;
if isempty(h)
C = imread('ngc6543a.jpg');
image(C,'CDataMapping','scaled');
h = line(0,0);
set(h,"Marker","o");
end
set(h,"XData", u);
set(h,"YData", u);
end
