This paper presents a novel image processing procedure dedicated to the automated detection of the medial axis of the root canal from dental micro CT records. The 3D model of root canal is built up from several hundreds of parallel cross sections, using image enhancement and an enhanced fuzzy cmeans based partitioning, center point detection in the segmented slice, three dimensional inner surfa...

Animating pictures is an interesting and useful visual effect in entertainment industry. In this paper, we present a system that allow user to animate a character in pictures in 3D space by applying 3D motion data. We use a 3D character mesh with skeleton rigged as template model. The user need to cut out silhouette of the character in pictures, and assign correspondence points between 2D chara...

First, the image is normalized to improve clarity of fingerprint image, and then cut accuracy feature extraction. Then smoothed reduce noise. Based on obvious directionality orientation, trend striations was analyzed by slicing method, based binarization refinement operation carried out eliminate skeleton fingerprint. When detail points are determined relationship between core can be compared d...

We present a Virtual Mirror system which is able to simulate a physically correct full-body mirror on a monitor. In addition, users can freely rotate the mirror image which allows them to look at themselves from the side or from the back, for example. This is achieved through a multiple camera system and visual hull based rendering. A real-time 3D reconstruction and rendering pipeline enables u...

A model based approach for rectifying the camera image of the bound document has been developed, i.e., the surface of the document is represented by a general cylindrical surface. The principle of using the model to unwrap the image is discussed. Practically, the skeleton of each horizontal text line is extracted to help estimate the parameter of the model, and rectify the images. To use the mo...

This paper deals with the use of some morphological tools for image and video coding. Mathematical morphology can be considered as a shape-oriented approach to signal processing, and some of its features make it very useful for compression. Rather than describing a coding algorithm, the purpose of this paper is to describe some morphological tools that have proved attractive for compression. Fo...

This paper presents a minutiae detection procedure based on adaptive tracing the gray-level ridge of the "ngerprint image with piecewise linear lines of di!erent length. The original "ngerprint image is smoothed with an adaptive-oriented smoothing "lter only at some selected points. This will greatly reduce the computational time. Each ridge in the skeleton is labeled with a number so that each...
