Variations on the CSC model
Ives Rey-Otero, Jeremias Sulam, Michael Elad
Over the past decade, the celebrated sparse representation model has achieved impressive results in various signal and image processing tasks. A convolutional version of this model…
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,…
Comparing Feature Detectors: A bias in the repeatability criteria, and how to correct it
Ives Rey-Otero, Mauricio Delbracio, Jean-Michel Morel
Most computer vision application rely on algorithms finding local correspondences between different images. These algorithms detect and compare stable local invariant descriptors c…
