Angular Quantization Online Hashing for Image Retrieval
2021
IEEE Access
Online hash method with fast search mechanism and compact index structure plays a pivotal role. The inner product between label data has become one of the important means to measure the similarity between existing data and new data streams in online hashing methods. However, due to its discrete attributes and semantic gap, it often leads to a large amount of information loss. In this article, we propose a new method called Angular Quantization Online Hashing (AQOH) to focus on learning compact
