I have the following binary image of an ear. I want to remove the vertical noisy lines from the left part of the image so that i get just the outline of the ear. I seem to fail to find a required filter which can do my job. I would be really obliged if I could get the answer to my question.

Try with more values, not 2, you may require to perform other morpho operations before applying bwareafilt.
Or do the edge detection more accurately, so that ROIs can be extracted easily.
