Gabor小波和变形模板的目标跟踪方法

Approach of target tracking adopting Gabor wavelet deformable template

在特征空间中利用Gabor小波和可变形模板实现了航拍图像中目标的跟踪.从图像中提取出一组具有特定参数的Gabor小波,并求出其权重作为目标特征,构成了Gabor小波特征模板.在跟踪过程中,随着目标的旋转、尺度等仿射变化,小波特征模板随之变形,优化了目标的仿射运动参数,实现了对目标的稳定跟踪.由于采用了基于Gabor小波的方法来搜寻最佳点的位置,使得搜寻结果更加精确有效.

An approach to track target of the aerial image using Gabor deformable template is presented in feature space. At fist distilling a set of Gabor wavelet with special parameter,and come out power value as the target feature, then constitute the Gabor feature template. Following the change of rotation, scale, will lead to the distortion of the template, which can keep optimizing affine sport parameter during tracking, the steady tracking can be realized. As adpting Gabor wavelet to search the best position, thus the better result will be precise and effective.
