中文摘要：

划格是准确定位cDNA芯片图像中杂交荧光样点并提取样点杂交强度信息必不可少的步骤，实现了一种基于爬山法的基因芯片图像自动划格算法，对NCBI上GEO数据库的cDNA基因芯片图像的测试结果表明，该算法能有效地对基因芯片点阵图像进行自动划格。

英文摘要：

Based on the fact that gridding is an indispensable stage of accurately identifying the location of each spot while extracting spot intensities from the microarray images, this paper realizes a hill-climbing based automatic gridding algorithm for cDNA microarray images. The experimental result of testing the cDNA microarray images shows that the calculation model can effectively detect the grids on cDNA microarray images.
