Figure 11

Examples of location of arrhythmias before and after filtering the texture for small clusters. The blue points show location of arrhythmia in non-filtered texture, the red point show the location of the arrhythmia in texture filtered for clusters with the size < 20. The filtered texture is represented by the yellow color. Case (c) shows almost the same position of the spiral wave rotation before and after filtration, while cases (a) and (b) show different positions of the arrhythmias in the texture.
