Microarray BASICA: background adjustment, segmentation, image compression and analysis of microarray images
This paper presents microarray BASICA: an integrated image processing tool for background adjustment, segmentation, image compression, and analysis of cDNAmicroarray images. BASICA uses a fast Mann-Whitney test-based algorithm to segment cDNA microarray images and performs postprocessing to eliminate the segmentation irregularities. The segmentation results, along with the foreground and backgr...
متن کاملLossless Microarray Image Compression by Hardware Array Compactor
Microarray technology is a new and powerful tool for concurrent monitoring of large number of genes expressions. Each microarray experiment produces hundreds of images. Each digital image requires a large storage space. Hence, real-time processing of these images and transmission of them necessitates efficient and custom-made lossless compression schemes. In this paper, we offer a new archi...
متن کاملBackground adjustment of cDNA microarray images by Maximum Entropy distributions
Many empirical studies have demonstrated the exquisite sensitivity of both traditional and novel statistical and machine intelligence algorithms to the method of background adjustment used to analyze microarray datasets. In this paper we develop a statistical framework that approaches background adjustment as a classic stochastic inverse problem, whose noise characteristics are given in terms o...
متن کاملCompression of microarray images
DNA microarrays have become a tool of paramount importance in the study of gene function, regulation, and interaction across large numbers of genes, and even entire genomes (Hegde et al., 2000; Moore, 2001). Microarray experiments generate pairs of 16 bits per pixel grayscale images (see Fig. 1, for an example). These images, which may require several tens of megabytes in order to be stored or ...
متن کاملLocal Smoothing Image Segmentation For Spotted Microarray Images
Gene microarray data are used in a large variety of applications, including pharmaceutical and clinical research. By comparing gene expression in normal and abnormal cells, microarrays can be used for identifying genes involved in particular diseases, and then these genes can be targeted by therapeutic drugs. Most gene expression data are produced from spotted microarray images. A spotted micro...
