A Review of Codebook Models in Patch-Based Visual Object Recognition [PDF]

Journal of Signal Processing Systems, 2011
The codebook model-based approach, while ignoring any structural aspect in vision, nonetheless provides state-of-the-art performances on current datasets.

Codebook+: A New Module for Creating Discriminative Codebooks

Multimedia and Expo, 2007 IEEE International Conference on, 2007
In this paper, we introduce a new module, Codebook+, into a classical framework which combines bag-of-words image representation with probabilistic latent semantic analysis (pLSA) for unsupervised object categorization. This new module makes the framework less sensitive to the image sampling methods as well as improves its performance.

Hierarchical codebook design for fast search with Grassmannian codebook

2012 IEEE Wireless Communications and Networking Conference (WCNC), 2012
It has been well known that channel aware systems (closed-loop) have better performance than channel unknown systems (open-loop). In order to know channel in the transmitter, receivers should send own channel information the transmitter through reverse channel.

Distributed optimization of codebooks

Signal Processing: Image Communication, 1995
Abstract Nowadays, many computer facilities are constituted by a network of general-purpose workstations. The aim of this paper is to show how to combine the available resources of this network in order to deal efficiently with time-consuming image processing algorithms.

Multilingual weighted codebooks

2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008
In this paper we present an approach for speech recognition of multiple languages with constrained resources on embedded devices. Examples of such systems are navigation systems, mobile phones and MP3 players. Speech recognizers on such systems are typically to-date semi-continuous speech recognizers, which are based on vector quantization.
