An analysis of the factors affecting keypoint stability in scale-space
Ives Rey-Otero, Jean-Michel Morel, Mauricio Delbracio
The most popular image matching algorithm SIFT, introduced by D. Lowe a decade ago, has proven to be sufficiently scale invariant to be used in numerous applications. In practice,…
Hand-held Video Deblurring via Efficient Fourier Aggregation
Mauricio Delbracio, Guillermo Sapiro
Videos captured with hand-held cameras often suffer from a significant amount of blur, mainly caused by the inevitable natural tremor of the photographer's hand. In this work, we p…
Removing Camera Shake via Weighted Fourier Burst Accumulation
Mauricio Delbracio, Guillermo Sapiro
Numerous recent approaches attempt to remove image blur due to camera shake, either with one or multiple input images, by explicitly solving an inverse and inherently ill-posed dec…
