Research of image segmentation technique applied in medical image processing
The mage segmentation is an important task in image processing.The image segmentation has great difficulty in the medical images because of the diversity and complexity of medical images.The threshold method becomes an important method of image segmentation as it's simple and efficient.But the threshold is not very satisfactory to the complex medical image segmentation.Powell algorithm is the best direct search method and the improved Powell method can do the targeted search better.An image segmentation method is introduced,which combines Otsu algorithm and Powell algorithm.The experiment result shows that the method can segment images fast and efficiently with robust.
