Performance evaluation of undersampled reconstruction using the blind compressed sensing (BCS), CS and low rank schemes: It can be seen that the proposed BCS scheme consistently produce the least mean square error at all undersampling factors. The CS, and low rank schemes depict loss in spatial features, and compromises due to motion blurring (see the yellow arrows in rows 3,4). In contrast, the proposed BCS scheme was found to be robust to motion blur, and provided superior spatio-temporal fidelity.
