Fire, especially wildfire, which can be considered as one of the main threats to vegetation cover and animals' life, has attracted lots of attention from environmental researchers. To better manage the fire crisis and take the necessary measures to c

Due to the existence of a large number of highly correlated parameters in the rational function model (RFM), known as rational polynomial coefficients (RPCs), RFM suffers from both ill-posedness and overparameterization problems. To tackle these prob

The existence of several unnecessary and highly correlated coefficients in the rational function model (RFM), known as rational polynomial coefficients (RPCs), leads to an ill-posed design matrix. Under such a condition, any small perturbation, inclu

Rational function model (RFM) is one of the most popular methods of geometrically correcting high-resolution satellite images (HRSIs). This model encounters overparameterization problem due to the existence of highly correlated RFM coefficients, name
