Abstract

Abstract: The traditional watershed segmentation algorithm is a kind of unsupervised segmentation algorithms，which produces sub-regions without semantic representation.A supervised image segmentation algorithm is proposed，which is based on Gaussian statistical property of sub-regions obtained by watershed segmentation.The proposed algorithm can learn the statistical model of background with a few labeled images，and then correctly separates the objects from background by merging the sub-regions which are judged members of the background.Experiments verify the validity of the proposed method.

Key words: background learning, supervised, segmentation, watershed algorithm

摘要： 传统的分水岭分割算法属于无监督的图像分割算法，分割获得的子区域往往不具备现实的语义信息。在分水岭分割的基础上，利用子区域像素值的高斯统计性质，提出了一种有监督的图像背景学习方法。该算法能够通过对少量人工标注的图像样本的学习，获得刻画背景子区域规律的统计模型。在此基础上对新图片中隶属于背景的子区域进行判断和合并，从而达到区分目标与背景的目的。实验验证了算法的有效性。
