Matlab 가이드 - 비디오에 대한 추가 정보 표시

Question

나는 U.I에 마우스 비디오를 표시하고 있으며 머리 부분의 좌표가있는 파일이 있습니다. 각 프레임마다 마커를 사용하여 머리의 위치를 ​​표시하고 싶습니다.

% --- Get the current frame, display it and set axes properties 
    setDirectory(handles.video,handles.numFrame); 
    I = handles.video.read();   
    imagesc(I,'Parent',handles.axes1); 
    hold on 
    plot(handles.xHead(handles.numFrame),handles.yHead(handles.numFrame),... 
      'o','MarkerFaceColor','b','MarkerSize',10,'Parent',handles.axes1); 
    colormap(gray); 
    handles.axes1.Visible = 'off'; 
    drawnow 
    hold off 

그리고 문제는 단지 비디오를 표시한다는 것입니다 내가 (콜백 버튼 포함)에이 과정을 일시 중지 할 때 현재 프레임없이 단지 지점을 표시 : 여기

내가 실제로 할 것입니다. ..

나는 주변을 둘러 보았지만 아무 것도 발견하지 못했습니다. 어떤 도움을 주시면 감사하겠습니다 :)

Thank you!

function play_Callback(hObject, ~, handles) 
% hObject handle to play (see GCBO)

% handles structure with handles and user data (see GUIDATA) 

% --- Inverse the value of the button Play/Pause when it is clicked

이 문제는 matlab에서 이벤트 대기열을 사용하는 방법과 drawnow가 이러한 대기열에 미치는 영향과 관련이 있습니다. 나는

이 즉시 업데이트하기 전에 처리 할 이벤트 큐에 이미 다른 콜백을 허용하지 않고 그래픽을 업데이트해야합니다

노출 drawnow 시도 할 것입니다.
