Comprehensive review of evolution of satellite sensor specifications against speedup performance of pattern recognition algorithms in remote sensing

The objectives of this study are as follows: (i) Discuss the necessity of HPC in remote sensing community towards contemporary scientific solution requirements; (ii) Investigate the speedup in performance of the template matching algorithm with FFT parallelization using hybrid Central Processing Units (CPUs)/Graphics Processing Units (GPUs); (iii) Apply the speedup algorithms for detection of real-time man-made structures such as buildings from remote sensing datasets, for constructing a 3-Dimensional city modelling.
