The objective of reduced-reference (RR) image quality assessment (IQA) is to evaluate the perceptual quality of the distorted image with only partial information of the reference image. A novel RR IQA which calculates the information entropy in the modified reorganized discrete cosine transform (RDCT) domain is introduced in this paper. Firstly, on the sender side, the modified RDCT is applied to...
POLAR is an experimental test-bed visualisation tool for Patterns of Life analysis, developed on the basis of knowledge elicitation with stakeholders. It uses multiple and coordinated views for exploring geo-temporal datasets. The system has three modes of interaction for addressing different kinds of PoL questions. It supports the exploration of movement patterns with resolutions ranging from intercontinental...
Remote sensing technique has become the main method for earth observation in the 21st century, and it has been widely used in environmental disaster monitoring and resources survey at regional and global scales. In recent years, remote sensing data type enriches constantly and presents to be mass data and multi-source increasingly. However, the utilization of remote sensing data remains at a low level,...
This investigation involved the formation and evolution of NO, HCN and NH3 during coal gasification. Since HCN and NH3 are the precursors of NOX, their summation are considered to show the characteristics of the precursors in this paper. The experiments were carried out in TGA with 25??C/min at atmospheric pressure. The releasing characteristics of the coal gasification species were inspected by the...
This paper investigates a new problem of visualizing a set of overlapping networks. We present two methods for constructing visualization of two and three overlapping networks in three dimensions. Our methods aim to achieve both drawing aesthetics (or conventions) for each individual network and exposing the common nodes between the overlapping networks. We evaluated our approaches using biological...
We describe a service-oriented approach to model, design, and implement biological processes and data. In particular, we summarize a novel service query framework to query bioinformatics services. Our approach treats biological data and computational tools as Web services. The query framework is part of an all-encompassing system that manages the end-to-end life-cycle of services, called Web Service...
In molecular biology, Gene Ontology (GO) has often been used for annotation and as a data mining dimension. A frequently performed step in microarray analytics is the clustering of co-expressed genes by their GO bioprocesses. Biological deductions are then made from the visual representation of the cluster pattern. Thus far, the question of how different representations of GO-annotated clusters affect...
Many dynamic networks have associated geological information. Here we present two complementing visual analysis methods for such networks. The first one provides an overview with summerized information while the second one presents a more detailed view. The geological information is encoded in the network layout, which is designed to help maintain user's mental map. We also combined visualization...
