本文描述了一种利用双树复小波来获得图像中关键点的丰富特征描述符的技术。主要目的是开发一种方法,用于保留完整的相位和振幅信息,从复杂的小波系数在每个尺度,同时提出的特征描述符的形式,允许任意旋转之间的候选人和参考图像补丁。
This paper describes a technique for using dual-tree complex wavelets to obtain rich feature descriptors of keypoints in images. The main aim has been to develop a method for retaining the full phase and amplitude information from the complex wavelet coefficients at each scale, while presenting the feature descriptors in a form that allows for arbitrary rotations between the candidate and reference image patches.
