On the basis of gap s temporal-spatial characteristics in and around source area before an earthquake, we propose a method to estimate characteristic parameters (characteristic distance and time) in the region-time-length (RTL) algorithm and introduce the method of correlation coefficient developed by some authors in 2006 to determine the characteristic parameters.

3D model retrieval technique by using two distance characters;

Feature distance based thresholding can be widely used for segmenting the obje.

Different from the previously popular kernel target alignment criteria,the new criterion overcomes the limitation and measures the performance of a combinatorial kernel matrix based on feature distance.

Image interpolation between the slices of ICT based on distance transformation;

In this paper,a new 3D soft-tissue visualization method is proposed,which consists of four steps: segmentation, distance transformation,peeling and volume rendering.

This method bases on distance transformation in Euclidean metric with the computational complexity of O((2+k)n),and is the same with non-Euclidean metric space.

Fast face detection based on skin color and distance transform

Combining distance transform and topological thinning, Distance Contained Centerline (DCC) algorithm is presented to extract a line-shaped skeleton of an elongated volume and compute the distance fro.

With an investigation on the algorithms of distance transform, this paper proposes an efficient algorithm for 3D raster buffer-generation based on isosurface propagation.
