Fig. 2From: Image-centric compression of protein structures improves space savings3D structure [27] and PIC compressor PNG image output for 2ign. Some attributes and symmetries in the 3D structure are observed in the corresponding PIC-compressed image. The upper and lower parts of the 3D structure of protein 2ign can be seen in PIC generated image as two separate masses of black pixels, one over the otherBack to article page
