Let I be a 3D digital image, and let Q(I) be the associated cubical complex. In this paper we show how to simplify the combinatorial structure of Q(I) and obtain a homeomorphic cellular complex P (I) with fewer cells. We introduce formulas for a diagonal approximation on a general polygon and use it to compute cup products on the cohomology H∗(P (I)). The cup product encodes important geometric...

We investigated performance improvement in a cellular system by introducing direct communication between terminals. Previous research has indicated that direct communication efficiently uses channels; however, this is not always so. We studied two factors that affect how much efficiency improves. One is the distribution of terminals. We defined some typical distributions with localization of te...

This paper discusses a research on web document analysis for companies listed on Bursa Malaysia which is the forerunner of financial and investment center in Malaysia. Data set used in this research are from the company web documents listed in the Main Board and Second Board on Bursa Malaysia. This research has used the Web Resources Extraction System which was developed by the research group m...

A large number of the presentations at this meeting are about boosting the spatial resolution of MRI. While there are several innovative approaches being pursued, these developments do not promise an image resolution better than of the order of a millimeter when considering MRI of large parts of the human body. This millimeter scale is three orders of magnitude coarser than the fundamental scal...

One of the important areas of current cellular research with substantial impacts on medicine is analyzing the spatial organization of genetic material within the cell nuclei. Higher-order chromatin structure has been shown to play essential roles in regulating fundamental cellular processes, like DNA transcription, replication, and repair. In this paper, we present an image analysis method for ...

Patrick Lemaire grew up in Orsay, close to Paris. He graduated from the Ecole Polytechnique and did his PhD at the EMBL (Heidelberg) and ENS (Paris) with Patrick Charnay (1985–1990); he then joined, as a post-doc, the laboratory of John Gurdon in Cambridge (1991–1994), where he identified a crucial Xenopus organizer gene, Siamois. He has been heading a CNRS research group in Marseille since 199...

Live-cell assays are used to study the dynamic functional cellular processes in high-content screening of drug discovery processes. The large amount of image data created during the screening requires automatic image-analysis procedures that can describe these dynamic processes. One class of tasks in this application is the tracking of cells and the description of the events and the changes in ...

Industry, in general, has entered into a new age. This can be readily seen in the scientific and technological advancements that have brought about a number of very important changes in the basic structure of industry. For example, today, most products are manufactured using some type of automatically controlled processing equipment. This equipment is often complex, demanding a variety of skill...

This paper shows the experimentation and the results obtained for LABERINTO research group at the ImageCLEF 2011 medical task. We focus our work on image retrieval based on textual information related to the image. The initial hypothesis is that query expansion could improve the effectiveness of image retrieval systems. In this proposal, three different types of indexes were built and several i...
