Influence of blur on feature matching and a geometric approach for photogrammetric deblurring
Blur Computer Vision Feature Matching Photogrammetry UAV
2014/9/9
Unmanned aerial vehicles (UAV) have become an interesting and active research topic for photogrammetry. Current research is based on images acquired by a UAV, which have a high ground resolution and g...
Adaptive Image Deblurring via Tanner Graph Representation and Belief Propagation
Adaptive Representation Belief Propagation
2013/7/24
Image deblurring aims to counteract the effect of point spread function (PSF) inimperfect image formation system. Conventional solutions include frequency-domainapproaches (e.g. Wiener filtering...
Application of Blind Deblurring Reconstruction Technique to SPECT Imaging
SPECT Imaging Blind Deblurring Reconstruction Technique
2009/9/7
An SPECT image can be approximated as the convolution of the ground truth spatial radioactivity with the system point spread function (PSF). The PSF of an SPECT system is determined by the combined ef...
Blind Deblurring Reconstruction Technique with Applications in PET Imaging
PET Imaging Blind Deblurring Reconstruction Technique
2009/9/4
We developed an empirical PET model taking into account system blurring and a blind iterative reconstruction scheme that estimates both the actual image and the point spread function of the system. Re...
