Sparse Representation Based SAR Vehicle Recognition along with Aspect Angle
Figure 1
Sparse representation examples for 3 different test targets: (a) SN_9563, (b) SN_C71, and (c) SN_132. From top to bottom: input test target, the corresponding sparse representation coefficient vector, and the reconstruction residual error. All the targets are represented by colors and markers distinct for each class, with red circle for SN_9563, blue square for SN_C71, and green diamond for SN_132, as shown in legend.
