I want to have Image file though ;h = surface(u,v,zeros(h,w),I);

h =

Surface with properties:
       EdgeColor: 'none'
       LineStyle: '-'
       FaceColor: 'interp'
    FaceLighting: 'flat'
       FaceAlpha: 1
           XData: [800×1067 double]
           YData: [800×1067 double]
           ZData: [800×1067 double]
           CData: [800×1067×3 uint8]

I used saveas(gif,’test.png’); but it dropped the quality of the image ( as I want to use it for text extraction), it is not acceptable. imshow, also has same problem. Thus, I use the surface. It makes good quality. But I cannot have image file. Is there any solution, for instance, use the h (output of surface) to make a image file.
