Multi-view object class recognition can be achieved using existing approaches for single-view object class recognition, by treating different views as entirely independent classes. This strategy requires a large amount of training data for many viewpoints, which can be costly to obtain. We describe a method for constructing a weak three-dimensional model from as few as two views of an object of...

This paper presents a calibration-free line-based tracking method to augment virtual objects into a video sequence. The presented method uses a cube on the first image to calibrate camera parameters. Then the 3D model for the cube is refined by adding 3D lines to its surface. For the remaining images in the sequence, the image lines are automatically detected and matched with their 3D correspon...

A parametric feature based jewelry modeler for designing and manufacturing of the Fret-worked bangles. These bangles are made from gold and adorned with fretwork designs. Fretwork is a decorative design that is either carved in low relief on a solid background, or cut out to adorn a jewelry item. Fretwork designs are viewed as features that are to be recurrently removed from the stock-solid ban...

The IBM Task Modeler supports the rapid creation and analysis of hierarchical task models, thereby providing a valuable and naturally visual tool for information architects. Task Modeler not only facilitates the essential processes of design, validation, and modification but also enables an information architect to develop and apply schemes for information classification.

The subject of the investigation is a volcanic rock in which a group of Neolithic tombs named "domus de janas" have been excavated. this operation is quite common in Sardinia, even if in this specific case it assumes some even more interesting characteristics. The research started gathering the 3D digital models with a high level of details and developing this virtual model with its great accur...

Segmentation is paramount to 3D video systems employing multi-view video-plus-depth data (MVD) to implement free-viewpoint navigation and comfortable 3D viewing, modeling, and comprehension. The Neutrosophic Set (NS) concept relies on the neutrosophy theory dealing with structures, and it focuses on the origin, scope, and nature of neutralities. NS used in this study is norm-entropy-based, and ...

Recent researches on Three-dimensional Geographic Information System (3D GIS) modeling technology were reviewed. The concept of 3D GIS modeling and its application in various fields were introduced. Essential techniques to realize 3D visualization were studied. A typical 3D GIS modeling usually contains the description and the transmission of GIS spatial data structure. GIS spatial data models ...

The problem of modeling large-scale virtual urban environments has remained challenging for computer graphics researchers and urban planners. Cities are difficult to model in detail, since they hold diverse and complex geometries. Building large-scale 3D city models by means of photogrammetric reconstruction is a time and resource intensive, often semi-automatic process and does not provide dat...

For the generation of freeform 3D models, one of the most intuitive solution is to use sketch-based modeling environments. Unfortunately, since the user interface relies upon the analyse of sketches in order to determine which action is requested by the user, the possible amount of different operations can be limited. In this paper, we present a 3D sketching system based on multiple views. Each...
