The process of converting an analog map into struc tured digitized information requires several di erent operations which are all time consuming when per formed manually Strictly automatic processing is not always a possible solution and an interactive approach can then be an alternative This paper describes a tool for map conversion fo cusing on the functionality for extraction of line struc t...

Hypercolumns in area V1 contain frequencyand orientation-selective simple and complex cells for line (bar) and edge coding, plus end-stopped cells for keypoint (vertex) detection. A single-scale (single-frequency) mathematical model of single and double end-stopped cells on the basis of Gabor filter responses was developed by Heitger et al. (1992 Vision Research 32 963-981). We developed an imp...

This paper describes a method for articulated 3D upper body tracking in monocular scenes using a graphical model to represent an articulated body structure. Belief propagation on factor graphs is used to compute the marginal probabilities of limbs. The body model is a loose-limbed model including attraction factors between adjacent limbs and constraints to reject poses resulting in collisions. ...

Much work has been done in the last few years on various aspects of automated map generalization. However, many of these efforts have been directed to the generalization of individual objects houses, roads, etc. while ignoring the spatial relationships between the objects themselves. This problem is particularly apparent where map generalization includes the simplification of contour lines (whi...

Contours maps (such as topographic maps) compress the information of a function over a two-dimensional area into a discrete set of closed lines that connect points of equal value (isolines), striking a fine balance between expressiveness and cognitive simplicity. They allow humans to perform many common sense reasoning tasks about the underlying function (e.g. elevation). This paper analyses an...

A series of imidazolium salt derivatives have demonstrated potent antitumor activity in prior research. A comprehensive in silicon method was carried out to identify the putative protein target and detailed structure-activity relationship of the compounds. The Topomer CoMFA and CoMSIA techniques were implemented during the investigation to obtain the relationship between the properties of the s...

In this paper, we introduce a method of generating a prosodic tree structure from the F0 contour of an utterance in order to analyze the information expressed by prosody in Japanese spontaneous dialogue. The connection rate, which means the strength of the relationship between two prosodic units, is de ned. By repeatedly combining the two adjacent prosodic units where the rate is high, the tree...

Mapping specific landform entities in the past is mainly achieved by manually examining contour lines on topographic maps. Automated delimitation of specific landform from digital elevation data remains difficult in geomorphologic mapping. This paper presents a method to automatically identify five common surface features of karst landscapes: isolated karst hill or sinkhole, clustered karst hil...

This paper carried out a classification study on the quality of different types apples. In order to achieve high-precision high-quality apples in various dimensions, shorten time, improve efficiency, and make it feasible for practical applications. proposes an automatic recognition model OB-Net (for apple appearance quality) based dual-branch structure. The consists two branches, O branch B bra...

During an 11 days mission in February 2000 the Shuttle Radar Topography Mission (SRTM) collected data over 80% of the Earth's land surface, for all areas between 60 degrees N and 56 degrees S latitude. Since SRTM data became available, many studies utilized them for application in topography and morphometric landscape analysis. Exploiting SRTM data for recognition and extraction of topographic ...
