Estimating 3-dimensional head pose from a single 2D image is a challenging task with extensive applications. Existing approaches lack the capability to deal with multiple pose-related and — unrelated factors in a uniform way. Most of them can provide only 1-dimensional yaw estimation and suffer from limited representation ability for out-of-sample testing inputs. These drawbacks limit their performance...
Head pose estimation from images is a challenging task with extensive applications. It has been attracting research attentions over decades and numerous approaches have been proposed. Among them, manifold embedding based methods, which assume that the pose variations lie on a low-dimensional manifold embedded in the high-dimensional feature space, have achieved great success. However, previous manifold...
Spaceborne SAR interferometry (InSAR) is a well known microwave remote sensing technique which has been applied for topography mapping and ground motion monitoring by exploiting phase difference from SAR data acquisition with relevant large spatial scale and high precision. The developed Permanent Scatterers Interferometry (PSI) is a further step of InSAR technique which offers a convenient processing...
In this paper, an improved approach for surface subsidence monitoring with SAR interferometry by using coherent point target is presented. A joint criterion of amplitude dispersion index and high spectral correlation criterion are proposed for coherent point target identification, which enable a flexible target selection in case of small or large volume of SAR data. Further more, in order to avid...
