Is there any way to do an operator on a specific region ?? for example I want to do imfill just on the Lower left quadrant of the page... I search and find blockproce but I could not do this for Lower left quadrant of the page??? thanks

Something like this would work.
[r,c]=size(BWImage);
rHalf=round(r/2);
cHalf=round(c/2);
lowerLeftQuadrant=BWImage(rHalf:r,1:cHalf);
lowerLeftQuadrant=imfill(lowerLeftQuadrant);
BWImage(rHalf:r,1:cHalf)= lowerLeftQuadrant;
Note that You can make the code shorter by replacing the last three lines of code as follow:
BWImage(rHalf:r,1:cHalf)= imfill( BWImage(rHalf:r,1:cHalf) );

A simple way is to simply chop it off:
% (Tune the numbers for what you need)
LowerLeftquad = my_image(74:end,1:30); % assuming a single frame of black & white.
LowerLeftquad = my_image(74:end,1:30,:); % assuming a single colour frame or many black & white.
Do what you want:
LowerLeftquad = imfill(LowerLeftquad);
And stick it back:
my_image(74:end,1:30) = LowerLeftquad;
