Changes in mean contrast-to-noise ratio (CNR) with concentration. (A) Mean CNR in the I decomposition over all tested concentrations of Au and over all spatial resolutions. (B) Mean CNR in the Au decomposition over all tested concentrations of I and over all spatial resolutions. Gray boxes denote the region of uncertainty in accordance with the Rose criterion (i.e. CNR ≤ 5). The independent and joint BF schemes improve the limits of detectability for I and Au by more than a factor two relative to classic BF. Cubic interpolation was used to connect sampled points.
