Shearlet-Based Structure-Aware Filtering for Hyperspectral and LiDAR Data Classification

Algorithm 1

ShearSAF for HSI and LiDAR feature extraction and classification.

1: INPUT: raw HSI data , LiDAR data ;

2: OUTPUT: the classification map ;

3: BEGIN

4: ,,,,;

5: using SNIC on to obtain the over-segmentation superpixel map with regions;

6: using KPCA on to obtain the information-focused HSI data ;

7: using equation (22) and (24) to obtain the texture and area information ,, and ;

8: using equation (33) to calculate the merging cost ;

9: conducting progressive region merging procedure on and obtain the final merging map , where the number of regions in is calculated by equation (39);
