𝐿𝑝-Norm Regularization in Volumetric Imaging of Cardiac Current Sources

Figure 4

(a) Source overlap (SO, vertical axis) obtained by 𝐿𝑝-norm reconstruction (1≤𝑝≤2, horizontal axis 1) for active sources with different extents (ranging from 1 to more than 80 active sources in the region, horizontal axis 2). (b)–(d) Examples of SO mean and standard deviation obtained by 𝐿𝑝-norm reconstruction (1≤𝑝≤2) for a region of (b) 1–10, (c) 20–30, and (d) 40–50 active sources.
