Finishing is the final phase of the gene sequencing process employed in the Human Genome Project. During the finishing process, analysts inspect and resolve ambiguous regions of DNA. While other phases of gene sequencing have evolved into high-volume, automated processes, finishing has remained manual, time-consuming, and costly. This thesis studies finishing as an example of a broader class of...

Image matching is an important task. There are many available methods for occluded image matching. In this paper we propose new simple image-matching algorithm, modified chamfer matching algorithm (MCMA). Distance transform and conventional chamfer matching algorithm are explained. Examples to demonstrate the algorithm and necessary results are also included. Proposed MCMA is robust, and to an ...

Abstract The tool geometry is generally of great significance in metal cutting performance. response surface method was used to optimize chamfer achieve reliable and minimum wear slot milling. Models were developed for edge chipping, rake wear, flank wear. adequacy the models verified using analysis variance at a 95% confidence level. Each optimized individually, multiple responses simultaneous...

Background and objective: Selecting a material with lower marginal gap is the key factor for successful dental prosthesis. With less of crown aggregation bacterial plaque at gingival margins, that result in periodontal diseases secondary caries could be limited. Methods: A mandibular right first molar sound tooth was prepared reference model according to preparations guideline heavy chamfer fin...

The steelmaking process consists of two phases: primary steelmaking and finishing lines. The scheduling of the continuous galvanizing lines (CGL) is regarded as the most difficult process among the finishing lines due to its multi-objective and highlyconstrained nature. In this paper, we present a multi-population parallel genetic algorithm (MPGA) with a new genetic representation called k near...

PURPOSE To compare marginal microleakage in porcelain veneer restorations following dental finishing using two types of instruments to test the hypothesis that microleakage will be less when teeth are prepared with sonic oscillating burs than when prepared with high-speed rotating burs. MATERIALS AND METHODS Fifty-six extracted human maxillary central incisors were selected and divided random...

This paper will examine the current chamfer and vector distance transforms for encoding objects as distance elds. A new vector distance transform is introduced which uses the city-block chamfer distance transform as a basis. Detailed error analysis using real CT data is presented demonstrating the improved accuracy the new approach gives over existing methods. The production of a sub-voxel accu...

We describe a shape-based chamfer matching method for recovering 3D hand pose using a monocular camera. Although some variants of chamfer matching methods incorporated edge direction information, of which the direction term is set empirically, so they may fail in different application scenario. In this paper, a collaborated directional chamfer matching (CDCM) is proposed. The direction term can...

Chamfer distances are discrete distances based on the propagation of local distances, or weights defined in a mask. The medial axis, i.e. the centers of the maximal disks (disks which are not contained in any other disk), is a powerful tool for shape representation and analysis. The extraction of maximal disks is performed in the general case with comparison tests involving look-up tables repre...
