How to organize our own input data and how to set srf transformation matrix？ #2

Open SdustZhangzhen opened 4 years ago

（1）The sample data ‘balloons_ms.mat’ under folder ‘data_cave' contains 'hyperHR, hyperLR, hyperHRI, multiHR, and W. When we do our own data for fusion with hyperspectral (hyperLR) and multispectral (multiHR) image , do we just input hyperLR and multiHR? And are the other data in balloons_ms.mat generated? If not, how do the hyperHR, hyperHRI, and W come？ （2）How to determine the 'srf' transformation matrix between airborne Hyperspectral and UAV multispectral data? Very thanks！

Hi, Thanks for your interesting in our work. 1) Right, the inputs are hyperLR and multiHR. The hyperHR is used to evaluate the reconstruction image. hyperHRI, and W are not used in this method.

2) The 'srf' is the matrix to compress the HSI data to MSI data in the spectral domain. We got the 'srf' from one of the compared methods, it is the spectral response matrix of Nikon D700. Please check the reference for SRF. You should be able to define it based on the spectral response of your sensor.
