How to remove straight lines from a Matlab image?

I have a matlab image from a matrix named Two_dim as shown in the figure below.

I would like to remove all 3 of the bottom straight horizontal lines from the image. I looked up on Stackoverflow to use regionprops to eliminate horizontal lines and obtained this code. But that doesn't seem to remove the lines.

rp = regionprops(Two_dim, 'PixelIdxList', 'Eccentricity', 'Orientation');
rp = rp([rp.Eccentricity]>0.95 & (abs([rp.Orientation])<2 | abs([rp.Orientation])>89));
Two_dim(vertcat(rp.PixelIdxList)) = false;
