Path following algorithms employ information from phase residues or data quality, typically in a independent mode for the difference between the distribution discreteness of residues and the distribution continuity of data quality values. Residues are taken as sources for interface propagation, and the quality of phase data weigh against the propagation velocity; then a combined application of residues...
Building digitalization is an important component of digital city development. Terrestrial laser scanning (TLS) technology provides a high-precision and high-density data source to guarantee building digitalization and reconstruction. However, when these large scattered points cloud are used to build a 3D digital model, the points of building boundaries extraction is an essential issue. In this paper,...
Change detection by unmixing has been shown to provide enhanced change detection performance for hyperspectral images with respect to more traditional approaches, especially when the temporal images contain sub-pixel level changes. In a recent paper, change detection by spectral unmixing was investigated in detail and the advantages that can be gained by using such an approach were systematically...
This paper proposes a simple polarimetric angle compensation to make accurate detection of deformed/inclined buildings possible by using quad-pol SAR data. It is expected that by applying the new compensation to the coherency matrix after doing conventional orientation angle compensation (OAC), undesired large surface scattering contribution generated between the inclined sidewall of the building...
