Matlab GUI面部跟蹤功能

Question

嗨，我正在創建一個Matlab GUI，允許攝像頭一旦執行面部跟蹤功能就能夠檢測到人的面部。但是，我只能檢測到臉部，但它不會跟蹤臉部。

% --- Executes on button press in Tracking. 
function Tracking_Callback(hObject, eventdata, handles) 
% hObject handle to pushbutton9 (see GCBO) 
% eventdata reserved - to be defined in a future version of MATLAB 
% handles structure with handles and user data (see GUIDATA) 
% hObject handle to startStopCamera (see GCBO) 
% eventdata reserved - to be defined in a future version of MATLAB 
% handles structure with handles and user data (see GUIDATA) 

% Create a cascade detector object. 
faceDetector = vision.CascadeObjectDetector(); 

% Read a video frame and run the detector. 
axes(handles.cameraAxes);  
frame = getsnapshot(handles.vid); 
bbox = step(faceDetector,frame); 


% Draw the bounding box around the face. 
rectangle('Position',bbox(1,:),'LineWidth',2,'EdgeColor',[1 1 0]); 

%Track the face over successive video frames until the video is finished. 
while ~isDone(handles.vid) 

% Extract the next video frame 
frame = getsnapshot(handles.vid); 
bbox = step(faceDetector,frame); 

% Insert a bounding box around the object being tracked 
rectangle('Position',bbox(1,:),'LineWidth',2,'EdgeColor',[1 1 0]); 


% Display the annotated video frame using the video player object 
getsnapshot(handles.vid); 

    end 

release(frame); 
release(handles.vid); 

我使用的圖像採集工具箱，並訪問了幾個網站，但我似乎無法解決問題。

任何幫助，非常感謝！
