A noise-resistant algorithm for grid finding in microarray image analysis
收藏 引用
MACHINE VISION AND APPLICATIONS 2006年 第5期17卷 337-345页
作者: Novikov, Eugene Barillot, Emmanuel Inst Curie Serv Bioinformat F-75248 Paris 05 France
We present an algorithm for automatic spot localization for microarray images with rectangular spot and block packing. As an input, the algorithm requires only the common array design parameters: number of block rows ... 详细信息

A robust algorithm for ratio estimation in two-color microarray experiments
收藏 引用
Journal of Bioinformatics and Computational Biology 2005年 第6期3卷 1411-1428页
作者: Novikov, Eugene Barillot, Emmanuel Service Bioinformatique Institut Curie 75248 Paris Cedex 05 26 Rue d'Ulm France
The reliability of the algorithms for ratio estimation in two-color microarray image analysis is very important, as these ratios build up the primary source of information for the subsequent analytical procedures (nor... 详细信息
