現在できている分がこんな感じで 動いた部分を差分で白くなるようにはできているのですが、そこから動くものをどうカウントしたらいいかわかりません。
clear all; close all;
runloop = true;
numPts = 0;
frameCount = 0;
%Create the webcam object.
cam = webcam();
video_tmp = snapshot(cam);
im_tmp=im2bw(video_tmp);
figure;
while runloop
%Capture one frame to get its size.
videoFrame = snapshot(cam);
im_video=im2bw(videoFrame);
subplot(1,3,1)
imshow(videoFrame);
subplot(1,3,2)
imshow(im_video);
subplot(1,3,3)
%imshowpair(im_video,im_tmp,'diff')
h=im_video-im_tmp;
imshow(h)
video_tmp=videoFrame;
im_tmp=im_video;
drawnow;
end
