That is not the border of the image. That is the perimeter of an object in the image, such as the liver. You need to segment out that region.

% Extract the individual red, green, and blue color channels.
redChannel = rgbImage(:, :, 1);
greenChannel = rgbImage(:, :, 2);
blueChannel = rgbImage(:, :, 3);
redChannel(1,:) = 0;
redChannel(end,:) = 0;
redChannel(:,1) = 0;
redChannel(:,end) = 0;
greenChannel(1,:) = 255;
greenChannel(end,:) = 255;
greenChannel(:,1) = 255;
greenChannel(:,end) = 255;
blueChannel(1,:) = 0;
blueChannel(end,:) = 0;
blueChannel(:,1) = 0;
blueChannel(:,end) = 0;
rgbImage = cat(3, redChannel, greenChannel , blueChannel);
