[Identification of Aaron's beard with clustering analysis by attenuation reflection-Fourier transform infrared spectrometry].
OBJECTIVE ::: To establish a new method to discriminate Aaron's beard by Fourier transformation infrared spectrometry. ::: ::: ::: METHODS ::: Attenuation Reflection-Fourier transformation infrared spectrometry with clustering analysis was used to the identification of Aaron's beard. ::: ::: ::: RESULTS ::: There were obvious differences in Aaron's beard. The results are consistent with that of morphologic study. ::: ::: ::: CONCLUSION ::: This method is rapid, simple and economical, and can be used to the quality control.
As massive data is stored in cloud datacenters, it is necessary to effectively locate interest data in such a distributed environment. However, since it is difficult to create a visual vocabulary due to the lack of global information, most existing systems of Content Based Image Retrieval (CBIR) only focus on global image features. In this paper, we propose a novel image retrieval framework, which efficiently incorporates the bag-of-visual-word model into Distributed Hash Tables (DHTs). Its key idea is to establish visual words for local image features by exploiting the merit of Locality Sensitive Hashing (LSH), so that similar image patches are most likely gathered into the same nodes without the knowledge of any global information. Extensive experimental results demonstrate that our approach yields high accuracy at very low cost, while keeping the load balanced.
