Creating the resulting image \(\mathcal {I}\), on which the compression techniques can be applied. The current figure is based on the example depicted in Fig. 18 and on the procedure illustrated by the flowchart in Fig. 17. In the current case, all images have a resolution of \(2^5 \times 2^5\) of pixels, meaning, that in \(\mathcal {I}_5\) the single squares correspond to individual pixels. While the green and red pixels mark pixel values of 1 and \(-1\), respectively, the gray background represents pixels with the value 0
