GDF: A Novel Image Fusion Approach for Compelling Depiction of Earthly Features
Algorithm 1
Geospatial data fusion (GDF).
| 1: Start GDF with Inputs: R, G, B, and PAN | | Where R, G, B, and represents the Red component, Green component, Blue component, and the matrix of the panchromatic image, respectively. | | 2: Compute intensity (I), which is average of RGB values, as per Equation (20). | | | 3: Calculate parameter K’s value using Elbow’s method. | | 4: Compute rearranged intensity Iadj as per the proposal in pan sharpening algorithm using Equation (21). | | | 5: Compute fusion components using Equations (22)–(24) | | | |
