Hello, I load a video in read mode on a matlab axis, I can resize it, but I can not resize the image generated by this video on the same axis

 system(['Detection\detectHello.exe Detection\haarman.xml Detection\haarechelle.xml ' filename]);       
        pause(2);
        xyloObj = VideoReader(filename);
        nFrames = xyloObj.NumberOfFrames;
        vidHeight = xyloObj.Height;
        vidWidth = xyloObj.Width;
        mov(1:nFrames) = ...
            struct('cdata', zeros(vidHeight, vidWidth, 3, 'uint8'),...
                   'colormap', []);
        for k = 1 : nFrames
            mov(k).cdata = imresize(read(xyloObj, k),0.55,'nearest');
        end   
        imag3 = imresize(imread('Image_finale.jpeg'), 0.55);
        axes(findobj('tag','ima3'));
        movie(mov, 1,xyloObj.FrameRate);
        imshow(imag3);
