We propose a superpixel-based classification method for finding area such as urban, land, lake etc. in SAR image. For classification, we use superpixel histograms as features. We compare the results of state-of-the-art superpixel methods with the one of recently proposed SAR image specific superpixel method. The test results obtained from a real TerraSAR-X image show that the SAR image specific method outperforms the state-of-the-art ones.
