MATLAB: Storing and update xy coordinate in realtime video

image acquisition

while ishandle(himg)
    trigger(depthVid);
    [depthMap,~, depthMetaData] = getdata(depthVid);
imshow(depthMap, [0 4096]);
    if sum(depthMetaData.IsSkeletonTracked) > 0
        skeletonJoints = depthMetaData.JointDepthIndices(:,:,depthMetaData.IsSkeletonTracked);
        hold on;
        plot(skeletonJoints(:,1), skeletonJoints(:,2),'*');
        hold off
    end
end
Is there any way i can update the data that i store in depthMetaData as shown in the coding? if yes what should i add in ? if no , is there other way around?

Best Answer

iwant = cell([],1) ;
count = 0 ;
while ishandle(himg)
    count = count+1 ;
    trigger(depthVid);
    [depthMap,~, depthMetaData] = getdata(depthVid);
    iwant{count} = depthMetaData ;
imshow(depthMap, [0 4096]);
    if sum(depthMetaData.IsSkeletonTracked) > 0
        skeletonJoints = depthMetaData.JointDepthIndices(:,:,depthMetaData.IsSkeletonTracked);
        hold on;
        plot(skeletonJoints(:,1), skeletonJoints(:,2),'*');
        hold off
    end
end
