Then Auto-level it. 3. posterize the image to 2 to only have pure b&w. 4. walk along the edges of the 480x480 square and floofill in white 5. paint every black pixel in white if it has less than N black neighbors. That's basically a Maximize morphological operator. Now only the DM should remain. 6. Crop the image to fit the DM 7. resize it to 14x14 with bilinear filtering. Note that you might need a pass of Minimize morphological operator if you used a simple Maximize morphomat operator in 5 8. posterize to 2 again, and voila. This process worked like a charm, in Photoshop, with your image.
