I did preprocessing steps (calibration, speckle filtering, terrain correction) for S1 data.
For S2 data I performed resampling for 4,3,2 bands (If I select all bands, the product is writing more than one hour and nothing happen), then I mosaic and mask my study area. Next I did the collocation by selecting S1 band as master product and S2 as slave. After that I applied PCA. But its loading and nothing happens. What was wrong and what should I do sir?
Thank you for these papers. I refered this. I have finished PCA and HPF. After that they have made standardization of PCA components and inverse gray processing for High Pass Filtered microwave data. I have no idea about these processes.
In this flow chart can you please explain how to do that all processes?
(RGB to IHS and inverse IHS transform, standardization of PCA components, inverse gray processing, density separation, histogram matching and multiplication of the results?)
sir ,I have a new ptoblem here,if i intend to fusion using sentinel-1 and sentinel-2 and to evaluate the accuracy of results.i got two methods to do that including create a stack and Collocate them,what the difference for the two ways?
