Back to h(hue),s (situration) ,v to HSV color space

hai I am working on flame detection vedio...First I aplied backroud subtraction methon on each frame of vedio. first the frame value is in RGB.Then I convert Into hsv....Then I convert this hsv to seprate channel H,S and V.Now after the processing I want to this unique channles to convert in one matrix means back to hsv.

for l=1:1
   frameForHsv = fc(:, :, :, l);  %l is frame Number
   hsvValues = rgb2hsv(frameForHsv );

     for m=1:height               
        for n=1:width 
         h(m,n)=hsvValues(m,n,1);

          s(m,n)=hsvValues(m,n,2);
          v(m,n)=hsvValues(m,n,3);

          if ((h(m,n)>=0 && h(m,n)<=60) && (s(m,n)>=0 && s(m,n)<=0.2)&&(v(m,n)>=127 && v(m,n)<=255) )
            newH(m,n)=h(m,n);
            newS(m,n)=s(m,n);
             newV(m,n)=v(m,n);
          else 
              newH(m,n)=0;
              newS(m,n)=0;
          end
       end
     end
    % Now how to this seprate channel newH,newS and newV into one Channel HSV?
 end

But those new images are masks. What do you intend to do with the masks? Maybe you should AND them together to get an overall mask. By the way, don't use for loops - it can be done faster vectorized in a couple of lines.
