if (size(x,3)>1)%if RGB image make gray scale
    try
        x=rgb2gray(x);%image toolbox dependent
    catch
        x=sum(double(x),3)/3;%if no image toolbox do simple sum
    end
end
x=double(x);%make sure the input is double format
[output,count,m,svec]=facefind(x);%full scan 
f = figure, imagesc(x);colormap(gray)%show image
plotbox(output,[],3)
 strtemp=strcat('C:\newframes9\',int2str(k),'.',pickind);

Please explain what happens instead of your expectations. It is much easier to solve a problem, when you do not have to guess at first, what the problem is.

Change

saveas(f, 'strtemp', 'bmp' )

to

saveas(f, strtemp, 'bmp' )

Only the save commands want the variable as string, but saveas wants the variable itself. A strange idea, but I think this decision was made 1984 and it cannot be changed anymore.
