I=imread('crack1.png');
I=rgb2gray(I);a=I;
I1= imfilter(I,gauss ) ;
s=strel('square',3);
h=imsubtract(imclose(a,s),a);
% IMG=double(imresize(h,[256 256]));
IMG=h;
imshow(h),figure,imshow(a)
level = graythresh(IMG);
BW = im2bw(IMG,level);
imshow(BW)
figure,imshow(BW)
SE = [strel('line' , 3 , 0)
    strel('line',3,45)
    strel('line',3,90)
    strel('line',3,135)] ;
ERED = BW-imerode ( BW ,s ) ;
figure,imshow(ERED)
BW2 = bwareaopen(ERED,100);
figure,imshow(BW2)
bw2 = imcomplement(BW2);
image2 = int8(bw2).*200;
figure,imshow(image2)

Where did you upload your images? So I can't see what you're seeing.

If you don't cast to double or 16 bit, your images will clip if their sum would be greater than 255. But I just see a bunch of morphology code, not code to add images.
