Moment invariants tracking algorithm for extended target;

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

Detection of extended target in complex background based on fractal features

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.

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

CFAR detection for range-extended target in Gaussian background;

The energy of target\'s echoes can not be sufficiently utilized when using the conventional statistical detection methods to detect the range-extended target of wideband high resolution radar(HRR),which affects the performance of radar detection.
