With the rise of digital photography and easy sharing of images over the internet, a huge amount of images with no notion of what they are showing exists. In order to overcome this problem, we – for the example of mountain recognition – introduce a method, that is able to automatically recognise a mountain shown in a photography. Our method does not require GPS information stored in the image, ...

Persons with Social Welfare Problems (PMKS) are individuals, community groups, or families who cannot adequately and properly meet their economic, physical, mental, social needs, both spiritually physically, because of an obstacle, difficulty, disturbance. This study aimed to classify sub-districts in Bojonegoro Regency based on the level welfare problems using K-Medoids Clustering (PAM) Analys...

We give conditions under which the worst-case size of the silhouette of a polytope is sub-linear.

Two of the best methods to recognize silhouette to create real-time volume shadow in virtual environment are described in this paper. Volume shadow algorithm is implemented for virtual environment with moveable illuminated light source. Triangular method and the Visible-non visible method are introduced. The recent traditional silhouette detection and implementation techniques used in volume sh...

A method for automatic removal of artifacts and errors that can appear in silhouettes extracted from polygonal meshes is presented and evaluated. These errors typically appear in polygonal silhouettes due to the discrete nature of meshes and numerical instabilities. The approach presented works in object space on silhouette curves made by chaining together silhouette edges and uses multiresolut...

Recent efforts attempt to combine together informations of different passive methods. Critical issues in this research are the choice of data and how to combine such data in order to increase the overall information. The combination of stereo matching and silhouette information has recently received considerable attention both for obtaining high quality 3D models and for modelling 3D dynamic sc...

In this contribution we present a silhouette based human motion estimation system. The system components contain silhouette extraction based on level sets, a correspondence module, which relates image data to model data and a pose estimation module. Experiments are done in a four camera setup and we estimate the model components with 21 degrees of freedom in two frames per second. Finally, we p...
