Identification of Curvature Features with Use of Boundary-Skeleton Model of Image
نویسنده
چکیده
A method of identification of curvature features for shape description and recognition is suggested. The method is based on the relation between local boundary features and the skeleton structure of a plain domain. It uses a continuous boundary-skeleton model of an image. The model consists of a boundary of a polygonal figure approximating a raster image, and a skeleton of the figure. To reveal curvature features the skeleton base representing fundamental structure of the image is used. A procedure of profile line segmentation from a face image based on the suggested method is presented. Key–Words: Boundary-skeleton model, skeleton base, curvature features, face profile segmentation

Landforms identification using neural network-self organizing map and SRTM data
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 ...

Skeleton is a thin version of the shape, which is a useful feature for shape description in image processing and computer vision. In skeleton extraction, it is an important task to compute a smooth and high quality medial function that can provide skeleton features easily and without noise. One of the main features for skeleton point detection is curvature maxima along the level-sets of the med...

The Hamilton-Jacobi approach has proven to be a powerful and elegant method for extracting the skeleton of two-dimensional (2-D) shapes. The approach is based on the observation that the normalized flux associated with the inward evolution of the object boundary at nonskeletal points tends to zero as the size of the integration area tends to zero, while the flux is negative at the locations of ...
