Robustness of the recovered images in noisy environments. a, e, and i The measured instantaneous intensities of \(\textbf{E}_{n} (\textbf{r})\) with \(\textrm{SNR} = -0.77\) dB, \(-6.53\) dB, and \(-13.47\) dB for the partially coherent vector beams with three-channel images “123” encoded inside. b–d, f–h, and g–l The corresponding recovered three-channel images in the noisy environments. m–p, q–t, and u–x The recovered color images in the noise environments with \(\textrm{SNR} = -0.17\) dB, \(-6.92\) dB, and \(-13.68\) dB, respective
