Dental biometrics used in forensic science for human identification. It utilizes dental radiographs. This radiograph provides information related to teeth shape, teeth contour and relative position of neighboring teeth, also it gives shapes of dental work like crowns, filling & bridges etc. This paper includes different method used for dental biometrics and related information. Dental biometric...

To other medical specialties, Dentistry can contribute for the identification of human remains after any disasters or crimes in assistance.By comparing post mortem and ante mortem dental radiographs,the algorithm can be developed.In addition to radiographs, this work aims to introduce photographic images.For dental images is proposed, in this research a contour and skeleton-based shape extracti...

A new method for extracting the boundary of the region of interest (ROI) from motion affected magnetic resonance images (MRI) is presented. An image pre-processing stage is included to suppress prominent ghost artifacts and excessive blurring in the background, in order to facilitate the contour extraction algorithm. The pre-processing stage consists of a novel fuzzy model, incorporating a tech...

Simple and fast feature extraction methods are in need today for Content Based Image Retrieval (CBIR) and object recognition applications. The work presented in this paper is contour based one dimensional shape feature extraction technique for closed contour objects. The continuous contour is normalized into ‘N’ representative points. The sector area based object area normalization (OAN) techni...

1 Recursive Context Reasoning for Human Detection and Parts Identi cation Liang Zhao and Chuck Thorpe The Robotics Institute Carnegie Mellon University Pittsburgh, PA 15213 Email: [email protected] Abstract Human detection and body parts identi cation are important and challenging problems in computer vision. High performance human detection depends on reliable contour extraction, but contour ex...

Nowadays, it rapidly increases that digital image information that stored locally or on internet, it has been an important issue that how to save and retrieve images in an effective way. Traditional manual classification can’t meet the actual needs. Now the method commonly used is to extract the image contour, it does not use the full image to deal with the image effectively. Currently, the eff...

The purposes of the CoPaSul toolkit are (1) automatic prosodic annotation and (2) prosodic feature extraction from syllable to utterance level. CoPaSul stands for contour-based, parametric, superpositional intonation stylization. In this framework intonation is represented as a superposition of global and local contours that are described parametrically in terms of polynomial coefficients. On t...

We present a method to extract the contour of geometric objects embedded in binary digital images using techniques in computational geometry. Rather than directly dealing with pixels as in traditional contour extraction methods, we process on object point set extracted from the image. The proposed algorithm works in four phases: point extraction, Euclidean graph construction, point linking and ...
