Hi,
Here is a simple solution:
clearvars
DD=imread('image.bmp');
figure(1), imshow(DD), title('Original')
MSK = DD > 25;
MSK = bwareaopen(MSK, 25);
MSK1 = imclearborder(MSK);
figure(2) % Compare Figure 1 and Figure 2
imshow(MSK1), shg, title('Cleaned')
Good luck.

Try
  • imclearborder() to remove blobs touching the edge of the image.
  • bwareafilt() to remove the largest blob(s) or blobs with areas in a certain range.
  • bwareaopen() to remove blobs smaller than a certain area.
