2. Obtain the gray-level gradient magnitude. 3. Derive the threshold surface by deforming the original image gray-level surface. 4. The threshold surface interpolation. 5. Segmentation based on the threshold surface. However, incomplete cells are still not detected reliably with this method. Double counting is sometimes occurred. In this paper, a Fuzzy Edge Detection Method is proposed. It is b...

1 In this paper I present some of the most important aspects for a rigorous discussion of analyticity properties of Schwinger functions for the ground state theory of a many-fermion system in one dimension. This proceeding is based on a work performed in Rome by G. Benfatto, G. Gallavotti, B. Scoppola and myself, to appear as a long paper 3] on Communications in Mathematical Physics with the ti...

There are several techniques to obtain boundary of an object in a digital image. Some of the well known techniques are contour tracing and edge detection technique. The result of this boundary tracing is used for analyzing an object in the image. This result is critical for some certain image analysis. In this study, the techniques will be used for obtaining the fish boundary from a digital ima...

This paper introduces a new method for data domain description , inspired by the Support Vector Machine by V.Vapnik, called the Support Vector Domain Description SVDD. This method computes a sphere shaped decision boundary with minimal volume around a set of objects. This data description can be used for novelty or outlier detection. It contains support vectors describing the sphere boundary an...

This paper discusses research results useful for producing a system which converts a two-dimensional computer sketch of a single homogeneous polyhedral object into a boundary representation solid model. An overview of our approach to such a system and its main algorithms is presented elsewhere. This paper gives more detail of some of the algorithms for categorising sketches according to the typ...

We describe the Sussex NLCL System entered in the NTCIR-7 Multilingual Opinion Analysis Task (MOAT). Our main focus is on the problem of portability of natural language processing systems across languages. Our system was the only one entered for all four of the MOAT languages, Japanese, English, and Simplified and Traditional Chinese. The system uses an almostunsupervised approach applied to tw...

This paper shows the use of a data domain description method, inspired by the support vector machine by Vapnik, called the support vector domain description (SVDD). This data description can be used for novelty or outlier detection. A spherically shaped decision boundary around a set of objects is constructed by a set of support vectors describing the sphere boundary. It has the possibility of ...

Automatic prominence or pitch accent detection is important as it can perform automatic prosodic annotation of speech corpora, as well as provide additional features in other tasks such as keyword detection. In this paper, we evaluate how accent detection performance changes according to different base units and what kind of boundary information is available. We compare word, syllable, and vowe...

This paper investigates how social images and image change detection techniques can be applied to identify the damages caused by natural disasters for disaster assessment. We propose a framework that takes advantages of near duplicate image detection and robust boundary matching for the change detection in disasters. First we perform the near duplicate detection by local interest point-based ma...

In this paper, we describe a new approach of shot boundary detection in digital videos which is able to detect not only hard cuts but special effects like wipes, fades, and dissolves as well. Our approach is divided into two steps – feature extraction and shot boundary detection. First, three different features for the measurement of shot boundaries within the video are extracted. Second, detec...
