There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract: This dissertation presents a novel convolutional dictionary learning algorithm for signals with a large number of channels. The algorithm uses low-rank updates for the dictionary, so that a matrix decomposition necessary for pursuit can be updated efficiently. The novel approach is applied to multi-layer dictionary models with multi-channel dictionaries and single-channel coefficients and demonstrated on the task of JPEG compression artifact removal.
