I have some images that look like the attached sample.
Is there a way to fill the white holes to make them into a clearer stripe image?
I have used imdilate, imclose, imfill but when I use them the tend to merge the stripes into one bulk. Is this because I'm using them in a wrong way?
Thanks for your help.

bwareafilt() could get rid of most of the disconnected white regions. It would not, however, get rid of the case like the middle right of the second image where there is a 2 x 2 square that happens to be touching the adjacent run of lines.
