Hello
I need to remove the upper border (red highligth) of this binarized image without affecting the bottom section, i haven't been able to figure out exactly which functions of the Image Processing Toolbox could help me.

Hi
Using morphological operations and connected components algorithm, the problem can be solved with the minor loss of bottom pixels.For example:
a=imread('imag.jpeg');
figure;imshow(a)
se = strel('line',8,90);
eroded = imerode(a,se);
b=logical(eroded);
st=regionprops('Table',b(:,:,1),'Area');
m=maxk(st.Area,2);
biggest = bwareafilt(b(:,:,1),[m(2) m(1)]);
figure;imshow(biggest)
dil=imdilate(biggest,se);
figure;imshow(dil)
The above code results in the below image. You can try with some other parameters of morphological processing and check if it will be more clear.
Hope it will helps.
