Hi everybody,
In my GUI I display a video live out of cam in an UIAxes. My plan is to plot detected markers in the image. Right know I don't know how to overlay the image and the plots in the same axes. Does anyone know how to solve this problem?
Best regards.

In addition here is my code:
if recognized_objects > 0
image(UIAXES,CURRENT_FRAME);
hold (UIAXES);
plot(UIAXES,CenterObjectsMatrix(:,1),CenterObjectsMatrix(:,2),'*r');
else
image(UIAXES, CURRENT_FRAME);
end

Hi,
From my understanding, you want to preview your live webcam Image on a UIAxes, and plot on the same UIAxes.
Inorder to get an idea on how to preview live webcam video in you GUI, you can refer to the following link
You can use the 'hold' and 'plot' functions to plot your markers on the same UIAxes as the image.
