ABSTRACT The primary purpose of this paper is to provide a novel wavelet-domain method for digital radiography with low dose examination. Approach of this study is an improved wavelet-transform-based method for potentially reducing radiation dose while maintaining clinically acceptable image quality. The wavelet algorithm integrates the advantages of wavelet-coefficient-weighted method and the existing Bayes Shr...

ABSTRACT Nowadays, while human requirements are extending, producing nanofibers and nanofiber based products are progressing rapidly. Nanofibers have received considerable study in recent years using various polymers and methods. PAN (Polyacrylonitryle) nanofibers have shown a great potential in producing nanofibers and nanofibre yarn as precursor polymers for making high performance carbon fiber. There is a lack of information about yarn ...

ABSTRACT This paper describes industrial sorting system, which is based on robot vision technology, introduces main image processing methodology used during development, and simulates algorithm with Matlab. Besides, we set up image processing algorithm library via C# program and realize recognition and location for regular geometry workpiece. Furthermore, we analyze camera model in vision algorithm library, calibrate the camera, process the image series, and resolve the identify problem for regular geometry workpiece with different colours.   KEYWORDS Machine Vision , Industrial Robot , Target Recognition , Image Processing Cite this paper Yan, J. and Yang, H.
