Seeking of tissue image digging point method based on genetic-arithmetic

For tissue-micro-array manufacture automatization, the fitness point seeking in the wax where the tissue sample to be picked up was studied. Based on digital image of tissue, the mathematical model of seeking was described as seeking the biggest inscribed circle center in the tissue area. The seeking method based on genetic-arithmetic was researched, including the code principle, parameters selection and the implementing method. The arithmetic improvement consists of fitness calculation and initialization selection, etc. The results of theory analysis and experiment prove that this arithmetic is effective and useful to fulfill the on-line manipulation.
