using two pairs of fine and coarse images

; the program can be used for whole tm scene and vi index product ; a fast version of estarfm code: improve the effeciency of original estarfm ; through controling the number of similar pixels ; developed by (1) zhu xiaolin,email: [email protected] ; department of land surveying and geo-informatics ; the hong kong polytechnic university ;
; debugging history: ; 1)5/12/2012 correct the abnormal prediction ; 2)9/29/2013 correct the spatial distance calculation for integrate window ; 3)7/10/2014 correct the abnormal value of spectral distance and use all bands to indentify background ; 4)2/13/2017 add one parameter to specify the value of pixels of background or missing ; 5)1/1/2018 improve efficiency and modified the weight for fusing vi index ; 6)3/11/2008 correct a bug in spatial distance caculation ; 7)7/27/2018 correct a bug of abnormal coversion coefficent estimation when the two input pairs are too similar ; 8)7/27/2018 improve the prediction when no enough simular pixels are selected ;
