To utilize all solutions produced,the augmented objective of each infeasible solution was defined in such way that the objective value of each feasible solution was not altered and that of each infeasible solution must be greater than that of the worst feasible solution.

Moment invariants tracking algorithm for extended target;

Segmentation for extended target in complex backgrounds based on clustering and fractal

Based on cross correlation coefficient and absolute difference algorithms and the principle of Hartmann Shack wavefront sensor, the feasibility of correlating Hartmann Shack wavefront sensor used for low contrast and extended object is studied according to the indoors solar granulation simulator.

For the low contrast extended objects such as solar granulation and the sunspot, the effectiveness of the cross-correlation coefficient and the absolute difference algorithms is studied.

ISA cannot be directly used to the high-resolution reconstruction of astronomical and space extended objective such as the sun or satellites so that this article discusses the possibilities of applying ISA to extended objective reconstruction by modification and carries out numerical simulation experiments of high resolution reconstruction of satellites under different photon noises.

Rebollo Neira discussed the reconstruction problem of wideband spreading function under the frame condition.

Based on the static performance of thermal imaging systems , a mathematical model for the visual range prediction adaptal for extended source target is studied.
