Figure 9

Comparison of abundance maps on Synthetic Data 2 with 20 dB white noise. From left column to right column are the abundance maps corresponding to Endmember 1, Endmember 4, and Endmember 9, respectively. From top row to bottom row are true abundance maps or abundance maps obtained by SUnSAL, CLSUnSAL, SUnSAL-TV, SOMP, SMP, RSFoBa, and BSOMP, respectively.
