still images is much more flexible in the sense that
real-time signal processing is not required. Thus, a
comparison of SR and NLSP for still images should
also be done. Further analysis is necessary before this
method can be implemented in an FPGA. An anal-
ysis of the high-frequency components generated by
the non-linear function used in the proposed method
and the original high-resolution image should also be
conducted.
