Take your binary image and smooth it then threshold at 0.5 and apply it.
windowSize = 9; % An odd number. Bigger = more smoothing.
kernel = ones(windowSize)/windowSize^2;
blurryMask = conv2(mask, kernel, 'same') > 0.5;
% Mask the image using bsxfun() function to multiply the mask by each channel individually.
maskedRgbImage = bsxfun(@times, rgbImage, cast(blurryMask, 'like', rgbImage));
