Gonzalo-Martin, Consuelo; Ji, Jiahao; Lillo-Saavedra, Mario; Garcia-Pedrero, Angel
PyOSIF provides a set of Jupiter Notebooks for Pansharpening and fusion of multispectral-multispectral imagery through multirresolution algorithms. In particular, three versions of the fusion based on the Wavelet à-trous Transform are included: the original algorithm, and two variants that allow the control of the spatial and spectral quality of the fused image. Other additional codes are included for resizing and downloading Google Earth Engine (GEE) Data Catalog imagery. The code allows you to use both GEE images and your own images.
