Feature points extraction is crucial for image segmentation and moving object modeling, and uniform sampling always causes lost of details. Illumination variation and noise also make the extracted feature points unreliable because of the sensitivity of classical detector to noise. A method based on 2D Gabor wavelet is presented to extract features, and a dynamic feature clustering based on feature GWT energy is used to compute the local feature points. The method is robust to noise and the features points extracted...

Feature points extraction is crucial for image segmentation and moving object modeling, and uniform sampling always causes lost of details. Illumination variation and noise also make the extracted feature points unreliable because of the sensitivity of classical detector to noise. A method based on 2D Gabor wavelet is presented to extract features, and a dynamic feature clustering based on feature GWT energy is used to compute the local feature points. The method is robust to noise and the features points extracted are very close to true local features. Active mesh based on image features can be generated by feature points extration. 

基于内容的图像分割和建立运动目标模型都需要选择图像的特征点,均匀采样会丢失过多的细节特征。图像受噪声和光照的影响,通常特征点不是很稳健,普通的边界检测算子和角点检测算子对噪声敏感,提出采用2DGabor小波变换计算目标的局部特征能量,利用能量系数进行特征点检测,能很好克服噪声的影响;然后采用基于能量系数加权的动态聚类,提取局部特征点,避免了聚类中心偏离实际特征部位。通过特征点提取,建立一种基于图像特征的主动网格

提出了基于图像内容特征的主动网格生成方法和网格节点运动估计方法,网格的边界与运动场景的边界有很好的一致性,避免了相同三角形小片内存在不同的运动物体,克服这种情况下运动估计失效的问题。块匹配的运动补偿方法的缺陷在于块效应,基于主动网格的运动补偿消除了块效应和边界不连续现象,运动场的估计与实际运动场有很好的近似,对局部运动也有更好的逼近。
