- 为了提高纹理图象分割的边缘准确性和区域一致性以及降低分割错误率, 提出了一种基于小波变换的利 用特征加权来进行纹理分割的方法. 该方法包括特征提取、预分割和后分割 3 个阶段, 其中, 特征提取在金字塔结 构小波变换的基础上进行 预分割利用均值聚类算法来对原始图象进行初步的分割 后分割则根据预分割的结果 对特征进行加权, 然后利用最小距离分类器来实现图象的最后分割. 与传统的方法相比, 该方法在分割错误率、边 缘准确性以及区域一致性等方面均有明显的改善-To imp rove t

- Active vision models can simplify visual tasks, provided that they can select sensible actions given incom-ing sensory inputs. Many active vision models have been proposed, but a comparative evaluation of these models is lacking. We present a compa
