In this paper, we propose an automatic alignment method for gel images in gel documentation devices. Electrophoresis gels are placed manually in gel documentation devices and thus the alignment of electrophoresis gels becomes wrong frequently. The proposed method rotates the pictured image bit by bit, calculates vertical profiles of all rotated images, and finally selects the rotated image with the highest standard deviation of vertical profiles as the aligned image. In experimental evaluation adopting practical agarose gel images used in industries, the proposed method aligns the agarose gel image precisely in all cases and increases the performance of image analysis by about 45% in the average case and 210% in the best case. Also, for some case of infeasible image analysis in the previous method due to severely wrong alignment, the proposed method makes its image analysis feasible through alignment correction.
