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);
