Hole Filling for View Synthesis Using Depth Guided Global Optimization

open access: yesIEEE Access, 2018
View synthesis is an effective way to generate multi-view contents from a limited number of views, and can be utilized for 2-D-to-3-D video conversion, multi-view video compression, and virtual reality. In the view synthesis techniques, depth-image-based

High-dimensional approximate nearest neighbor: k-d Generalized Randomized Forests [PDF]

open access: yes, 2016
We propose a new data-structure, the generalized randomized kd forest, or kgeraf, for approximate nearest neighbor searching in high dimensions. In particular, we introduce new randomization techniques to specify a set of independently constructed trees ...

Online Product Quantization

open access: yes, 2018
Approximate nearest neighbor (ANN) search has achieved great success in many tasks. However, existing popular methods for ANN search, such as hashing and quantization methods, are designed for static databases only.

Tree-based Search Graph for Approximate Nearest Neighbor Search

open access: yes, 2022
Nearest neighbor search supports important applications in many domains, such as database, machine learning, computer vision. Since the computational cost for accurate search is too high, the community turned to the research of approximate nearest neighbor search (ANNS). Among them, graph-based algorithm is one of the most important branches.

Joint K-Means quantization for Approximate Nearest Neighbor Search

open access: yes2016 23rd International Conference on Pattern Recognition (ICPR), 2016
Recently, Approximate Nearest Neighbor (ANN) Search has become a very popular approach for similarity search on large-scale datasets. In this paper, we propose a novel vector quantization method for ANN, which introduces a joint multi-layer K-Means clustering solution for determination of the codebooks.
