MATLAB: How can i draw a slanted rectangle in a frame

graphicsimage processingvideo processing

I have a code that takes a video,split it into frames and then asks me how many rectangles would i like to draw on the frame (the first one). In those rectangles the mean intensity in each frame is calculated.I would like to be able to draw a slanted rectangles too.Is there any command that can help me?Here is the part of my code that is responsible for making the rectangles:
 if k==1
    result=input('How many rectangles would you like to draw? ');
    pos=zeros(result,4); 
    for i=1:result
    handle=imrect;
    pos(i,:)=handle.getPosition;
    end
end

Best Answer

You could call the line() command 4 times to draw the sides of your slanted rectangle in the graphical overlay above the image. Alternatively, if the user needs to adjust the vertices, you can call impoly().
