I had a code for face detection using vision.CascadeObjectDetector in real time and i want to input the code into a gui with 1 start buttona and 1 axes. I had try by editing this code
if true
obj = imaq.VideoDevice('winvideo',1,'YUY2_320x240');
set(obj,'ReturnedColorSpace','rgb');
figure('menubar','none','tag','webcam');
% tell matlab to start the webcam on user request, not automatically
triggerconfig(obj, 'manual');
% we need this to know the image height and width
vidRes = get(obj, 'VideoResolution');
% image width
imWidth = vidRes(1);
% image height
imHeight = vidRes(2);
% number of bands of our image (should be 3 because it's RGB)
nBands = get(obj, 'NumberOfBands');
% create an empty image container and show it on axPreview
hImage = image(zeros(imHeight, imWidth, nBands), 'parent', handles.axPreview);
% begin the webcam preview
preview(obj, hImage);
end
into this
if true
obj = imaq.VideoDevice('winvideo',1,'YUY2_320x240');
set(obj,'ReturnedColorSpace','rgb');
figure('menubar','none','tag','webcam');
% tell matlab to start the webcam on user request, not automatically
triggerconfig(obj, 'manual');
while(true)
frame=step(obj);
%Detect faces.
bboxes = step(faceDetector,frame);
%Annotate detected faces.
IFaces = insertObjectAnnotation(frame,'rectangle',bboxes,'face');
hImage = image(IFaces,'border','tight', handles.axPreview);
% begin the webcam preview
preview(obj, hImage);
end
but failed. Could anyone teach me how to input both the webcam and the bounding box of the face in real time into the same axes? Thanks.
