Compared with conventional techniques employing manually defined dictionaries, such as Fourier Transform and Wavelet Transform, dictionary learning aims at obtaining a dictionary adaptively from the data so as to support optimal sparse representation of the data. In contrast to conventional clustering algorithms like K-means, where a data point is associated with only one cluster center, in a dictionary-based representation, a data point can be associated with a small set of dictionary atoms. Thus, dictionary learning provides a more flexible representation of data and may have the potential to capture more relevant features from the original feature space of the data. One of the early algorithms for dictionary learning is K-SVD. In recent years, many variations/extensions of K-SVD and other new algorithms have been proposed, with some aiming at adding discriminative capability to the dictionary, and some attempting to model the relationship of multiple dictionaries. One prominent application of dictionary learning is in the general field of visual computing, where long-standing challenges have seen promising new solutions based on sparse representation with learned dictionaries. With a timely review of recent advances of dictionary learning in visual computing, covering the most recent literature with an emphasis on papers after 2008, this book provides a systematic presentation of the general methodologies, specific algorithms, and examples of applications for those who wish to have a quick start on this subject.Synthesis Lectures on Image, Video, and Multimedia Processing,1559-8144EngineeringElectrical engineeringSignal processingTechnology and EngineeringElectrical and Electronic EngineeringSignal, Speech and Image Processing Engineering.Electrical engineering.Signal processing.Technology and Engineering.Electrical and Electronic Engineering.Signal, Speech and Image Processing .620Zhang Qiangauthttp://id.loc.gov/vocabulary/relators/aut433648Li Baoxinauthttp://id.loc.gov/vocabulary/relators/autBOOK9910795633803321Dictionary Learning in Visual Computing3826121UNINA
