A novel rapid vacuum pressure swing adsorption process with intermediate gas pressurization for producing oxygen is proposed to improve the performance of miniature oxygen concentrator based rapid pressure swing adsorption technology. The effects of intermediate gas pressurization and desorption pressure on the performance of the process are evaluated by experiments and simulations. Results showed...
Image stitching is used to combine several individual images having some overlap into a composite image. In this paper, a novel wavelet based seamless image stitching algorithm is introduced, where the dissimilarity is defined in the gradient and curvature domain. In order to reduce the artifacts in image stitching due to the misalignment of image registration, we design a new energy function combining...
Texture retrieval is a vital branch of content-based image retrieval. Rotation-invariant texture retrieval plays a key role in texture retrieval. This paper addresses three major issues in rotation-invariant texture retrieval: how to select the texture measurement methods, how to alleviate the influence of rotation for texture retrieval and how to apply the proper multi-scale analysis theory for texture...
The work presented in this paper is an attempt to bridge two co-existing realties: Semantic information and MultiAgent Systems, the aim is to provide multi-domain experts or users with uniform semantic interoperability framework in heterogeneous distributed environment. We focus on the domain Ontology's original data source remote sensing imagery, bridging gap of the high-level semantic information...
Due to the low signal-to-noise ratio and the relatively small objects of infrared image, we propose a novel improved object detection algorithm. In our algorithm three customer variables such as Gaussian background model deviation (GBMD), relative radiation intensity difference (RRID) and region correlation (RC) have been defined to describe information of the target local region texture characteristics,...
