Image gridding algorithm for DNA microarray analyser

A deoxyribonucleic acid (DNA) microarray is a powerful tool that is widely used in genetics to monitor the expression levels of thousands of genes in parallel. Gridding, segmentation and intensity extraction is the process of gene expression. In the process of gene expression, gridding process information leading to dig their own DNA and provide coordinates for each point. Gridding can be implemented by using three kinds of process which is manual, semi-automatic and fully automatic. Well-organized and easy automatic gridding method for DNA microarray image analysis was proposed in this paper. Five popular techniques for DNA microarray gridding are evaluated with highlighted on gridding accuracy, processing time and capability of noise removal.
