Thematic information detection is an important application of remote sensing image. Support vector machine (SVM) has been widely used in MODIS remote sensing detection. However, the difficulty of SVM application is how to select the suitable kernel function for remote sensing image. In this paper, the Sangeang Api volcanic ash cloud on May 30, 2014 is taken as an example, and the linear, polynomial,...
With the increasing demand for high resolution, large scale images and fast downlink data rates of remote-sensing satellites, the higher decoding speed of BM(Berlekamp Massey) algorithm of the satellite receivers employing RS(Reed Solomon) codes as forward error correction codes is needed. A new improved BM algorithm is presented and its explicit proofs are given. Taking RS(255, 223) of CCSDS standard...
In this work we describe cyclic code on ℤp2 by polynomial representation, we also discuss polynomial representation of Nechaev permutation and the Gray and Nechaev-Gray maps. Then we extend Gerardo Vega and Jacques Wolfman's result in [1] on ℤ4 to ℤp2 by polynomial representation of Gray and Nechaev-Gray maps. We proved that from a linear code ℤp2 of length n a linear cyclic code on ℤp of length pn...
