I've attached an image after doing this to it:

1. InvertCommand
2. GrayScaleCommand to convert the image to 8bpp
3. GaussianCommand using a radius of 1
4. IntensityDetectCommand with low of 200 and high of 255
5. ColorResolutionCommand to convert image back to 1bpp
6. InvertCommand

The main factors here are the GaussianCommand which blurs the edges so that intensity detect will have something to work with.  There are other blurring images like AntiAliasingCommand, RadialBlurCommand but Gaussian is the simplest and why I chose it.  You can increase the blurring by increasing the radius.  Second is the IntensityDetectCommand which will make the image black and white, any intensities between the low and high  and above the high black, anything below the low white.  I'd play with these two functions to get the results that you want.
