drawframe(1);

Write your drawframe function below

function drawframe(f)
persistent imCData
if(f==1) % Get image data for the pout sample image
    I = imshow('pout.tif');
    imCData = I.CData;
    clf
end
s = size(imCData); % Get sixe of image for axis scaling
if(f<=8) % Show original image in grayscale
    surf(1:s(1),1:s(2),imCData','LineStyle','none');
    colormap(gray);
else
    BW = edge(imCData,'canny'); % use canny edge detection
    if(f<=16) % grayscale plot of edge detected image
        surf(1:s(1),1:s(2),BW'*2,'LineStyle','none');
        colormap(gray);
    else % then show various different color schemes using a custom colormap
        cmap = [1 .1 .9;.9 .8 .7;1 .4 .2;.9 .9 .7;.1 .7 .9;1 1 0;.95 .3 .3;.2 .3 .2];
        if(f<=24)
            surf(1:s(1),1:s(2),BW'*2,'LineStyle','none');
        elseif(f<=32)
            surf(1:s(1),1:s(2),4+BW'*2,'LineStyle','none');
        elseif(f<=40)
            surf(1:s(1),1:s(2),8+BW'*2,'LineStyle','none');
        else
            surf(1:s(1),1:s(2),12+BW'*2,'LineStyle','none');
        end    
        colormap(cmap);
        clim([0 14]);
    end
end
% Set image properties
view([90 90]);
axis([1 s(1) 1 s(2)]);
set(gca,'Color','k','XTick',[],'YTick',[]);
set(gcf,'Color','k');
end
