Hello,
I am trying to lear how I can remove the small objects to find the main area of the image (the black section between the long lines (edges)? I want ot get rid of external and internal objects.
Thanks for the helps

#Approximate Here
se = strel('line',3,3);
BW1=imdilate(binaryImage,se);
BW2=bwareafilt(~BW1,1);
se = strel('line',3,3);
BW3=imerode(BW2,se);
se=strel('disk',7);
result=imclose(BW3,se);
imshow(result);

#Try
BW = rgb2gray(imread('Capture.png'));
figure,imshow(BW)
BW = imbinarize(BW);
se = strel('line',3,3);
BW1=imdilate(BW,se);
BW2=bwareafilt(~BW1,1);
se = strel('line',3,3);
BW3=imerode(BW2,se);
se=strel('disk',7);
result=imclose(BW3,se);
figure,imshow(result);

Looks like you're doing an edge detection for some reason. Can I see the original image? Because usually edge detection is NOT what you want to do, for exactly the reasons you are seeing. It would probably be better to use a different segmentation method, like thresholding.

I changed the keyword to subject. It looks like the images are no longer there for some reason, perhaps because you took them down from your site.
