Revisiting Multi-Codebook Quantization

IEEE Transactions on Image Processing, 2023
Multi-Codebook Quantization (MCQ) is a generalized version of existing codebook-based quantizations for Approximate Nearest Neighbor (ANN) search. Specifically, MCQ picks one codeword for each sub-codebook independently and takes the sum of picked codewords to approximate the original vector.

Beyond Explicit Codebook Generation: Visual Representation Using Implicitly Transferred Codebooks

IEEE Transactions on Image Processing, 2015
The bag-of-visual-words model plays a very important role for visual applications. Local features are first extracted and then encoded to get the histogram-based image representation. To encode local features, a proper codebook is needed. Usually, the codebook has to be generated for each data set which means the codebook is data set dependent. Besides,

GLARE: Low Light Image Enhancement via Generative Latent Feature based Codebook Retrieval

European Conference on Computer Vision
Most existing Low-light Image Enhancement (LLIE) methods either directly map Low-Light (LL) to Normal-Light (NL) images or use semantic or illumination maps as guides.
