HDIdx: High-dimensional indexing for efficient approximate nearest neighbor search

Ji Wan, Sheng Tang, Yongdong Zhang, Jintao Li, Pengcheng Wu, Steven C.H. Hoi
2017 Neurocomputing  
In this work, we present "HDIdx", an efficient high-dimensional indexing library for fast approximate NN search, which is open-source and written in Python.  ...  Fast Nearest Neighbor (NN) search is a fundamental challenge in large-scale data processing and analytics, particularly for analyzing multimedia contents which are often of high dimensionality.  ...  Conclusions This work presented the HDIdx software that offers cutting-edge solutions for indexing largescale high-dimensional data.  ...

Improved Earth Observation Data Retrieval through Hashing Algorithms

A.-C. Grivei, C. Vaduva, M. Datcu
2019 IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium  
In order to increase the search speed through data warehouses for knowledge discovery, new indexing methods are required to handle both the size and the informational complexity of EO data.  ...  In this paper, we propose a methodology that combines feature extraction, hashing methods and optimized indexing to convert the images characteristics into hash codes in an effort to speed up the search  ...  A product quantization method for approximate nearest neighbor search is presented in [4] . Combined with an inverted file system provides high efficiency.  ...

Deep learning hashing for mobile visual search

Wu Liu, Huadong Ma, Heng Qi, Dong Zhao, Zhineng Chen
2017 EURASIP Journal on Image and Video Processing  
As the particular challenges of mobile visual search, achieving high recognition bitrate becomes the consistent target of existed related works.  ...  In this paper, we explore to holistically exploit the deep learning-based hashing methods for more robust and instant mobile visual search.  ...  Deep learning hashing 1.3.1 Background Hashing, a widely-studied solution to approximate nearest neighbor search, aims to transform the data item to a low-dimensional representation, or equivalently a  ...
