ABSTRACT
Automatic gene-chip image grid localization is an essential task for gene-chip image analysis. Now an method based on profiles of gene-chip image is proposed. Using the differences between two profiles after filtration by arithmetic mean method, we can easily find the local grayscale minimum between two probe spots, then the probe spots are automatically located. The experiments show that the new approach correctly locates the probes while giving protection against noise affection robustly. Grid location
