Despite the widespread application of microarray imaging for biomedical research, barriers still exist regarding its reliability and reproducibility for clinical use. A critical problem lies in accurate spot segmentation and quantification of gene expression level (mRNA) from microarray images. A variety of commercial and research freeware packages are available, but most cannot handle array spots...
This paper presented circular scanning synthetic aperture radar (SAR) based on circular scanning antenna. The work principle of this scanning radar was described. The variations of synthetic, aperture time, azimuth resolution and time-bandwidth product were analyzed. Also a focused imaging algorithm instead of DBS was used to form high resolution image. This algorithm based on extended chirp scaling...
Image Multi-threshold Segmentation techniques are the important contents of image segmentation, one typical algorithm of which is Fuzzy C-Means (FCM) clustering segmentation algorithm. The conventional FCM clustering algorithm is based only on special information and ignores the spatial distribution of pixels in an image. Large numbers of improved methods are put forward to conquer this limitation,...
