在图像特征提取、识别以及基于特征的图像压缩等领域内，作为关键技术的图像分割方法具有重要的地位。本文首先对基于区域的图像分割技术进行了介绍。然后针对静态位图图像，利用基于链码的分水岭算法对图像进行分割．达到与人视觉系统比较符合的分割结果。-In the image feature extraction, recognition and feature-based image compression and other areas, as a key technology for image segmentation method has an important role. This first region-based image segmentation technique is described. Then the static bitmap image, using the watershed algorithm based on chain code for image segmentation. Comparison with the human visual system to meet the segmentation results.
